The $99 China LCD-scopes beat heck out of a fine old Tektronix which "needs work" you can't manage.[/QUOTE]
Could you please suggest/link something. Would be useful to me too. Thanks.

A working scope is always more useful than a broken one.
The Rigol mentioned above seems the most popular. There are more software hacks for it than any other out there. They are also relatively affordable. The common price is around $400. They are even available from Walmart.com.

no, nothing exotic or special. it was a good, first scope for me many years ago.
it still works well and I'm saving it for my grandson.
cheap (no heavy power supply so shipping won't break the bank), very easy to use, cursor measurements are handy.
last time i needed to, you could fix it when needed with no unobtanium parts.

The TEK5000 series scopes are usually sold for give-away prices. While low-bandwidth, they are also very low noise and were used by medical equipment and automotive companies. They have some really great plug-ins. I have an almost new 5223 which was liberated from a "pacemaker" company in the midwest. I also have a 5103N which was used by a defense contractor.
Most of the time, the 3012B or 2465B are my go-to scopes, and they are both quite ancient by modern standards. I did buy a Digilent for looking at data-lines, but only use it for that purpose.
I recently bought a digital scope, a Rigol 2072 I think is the model number. I have always used analog scopes but my HP boat anchor scope burned up and I decided to try a digital scope. The dig. scope works great for catching glitches, capturing and analyzing waveforms and general measurements but IMO it is no match for a good analog scope for low level ac trouble shooting. I found the learning curve rather steep and it takes some time to get used to all the features and how to put them to use. I am still learning about it. In my case a ham radio operator friend of mine turned up 3 TEK 465 scopes. A 465, a 465B and a 465M. Only one was working but I got the 465b working and he is letting me keep the 465m which needs a repair in 1 channel when I get a chance. I find the 465 scopes are a great complement to a digital scope.
These 40year old scopes are big and heavy but are still serviceable in many cases and have 100mhz bandwidth and excellent triggering. You can probably find one for a reasonable cost. Ham radio fests and radio operators are good sources of information about used test equipment IME.

There is a new version of the Analog Discovery, same price, allows use of external power supply, less crosstalk between channels: Affordable and portable USB oscilloscope, logic analyzer, function generator, and digital I/O
I bought the Siglent SDS1052DL this week and it is a pleasure to use compared to the old Tektronix analog scope I have. I am loving the auto feature where one does not have to fiddle with knobs and switches to display the signal correctly. The reviews were good on Amazon and the price is right for a new scope that works. If it last it is all the scope I will ever need.

I remember noticing some low cost palm-sized O'scopes on ebay:
DSO112A Handheld Portable USB Digital Storage Oscilloscope TFT Touch Screen J3P0
And I remember a cute all-valve O'scope somebody had built!

Price is indeed good on Amazon at 259. Was thinking about buying a refurb Tek465 as my first scope but now considering something like the Siglent since its about the same price. Did you also consider the SDS1102CML+ for 319 and the Hantek DSO5102P for 264? Since you are more experienced with scopes than I am would appreciate your insights. What are you using for a signal generator? Thanks.

I considered this one, Rigol DS1054Z at $399, which can be unlocked pretty easily to have a much higher end scope but I feel like the Siglent will fulfil all my needs and is all the scope I need for audio work and save some money as well. I have some cheap signal generators already but decided to get a good cheap one and settled on the KKmoon DDS dual channel at Amazon for $55. Both these pieces of equipment are what I consider hobby grade but that is all I am going to do with them. For someone that is in the electronic field they would probably be better off buying better named equipment.
I do not have that much experience with scopes, very little actually. I do have an old analog that is a pain for me to use because I did not use it that often and have to study how to use it everytime I play with it. A lot to do with being 68 years old this month. I have been wanting a new scope though since I was 18 or 19 years old and took a few courses in electronics and did some car radio repairs. Easy learning curve with these new digital scopes. I watched a few youtube videos this morning and immediately tested a couple of amps and a couple of pres.
