Very nice little two channels scope that plug on USB, great to use on a laptop.
It even includes the schematic, and how to right the code... At 249$ it is quite reasonable. Can be the solution for you guys working in your basement

The sample rate is a bit low for the price.

PC scopes tend to be very limited. Especially their front ends are limited with 200 mV/div as the highest sensitivity. Measuring higher voltages is easily accommodated with an attenuating probe 10x, 100x, 1000x are commonly available. But there is no substitute for a good analog front end. For $250 you could get a pretty nice used Tektronix scope. That would be my choice any day. But hey... Maybe I'm just old fashioned...

Unless you absolutely need the raw data, a digital camera works fine for waveform capture on a real oscilloscope. It's been done that way for decades -- starting with Polaroid film back in the day... Love the old Tek scopes. My 2215 (2-ch, 60 MHz) and 2465B (4-ch, 500 MHz) are still ticking.

what about the RIGOL DS1052E digital scopes? They are just a tad bit more expensive at $400 from hong kong and they seem to have rich functionality. I used old tek analog scopes when i went to school 20 years ago, but i don't know how keen i'm at buying one of those old bricks on ebay. The new scopes smaller footprint is very attractive to me, and i kind of like to have a new scope with warranty over something 15-20 year old which i don't know if i could fix myself if needed.
I use everyday a Tektronix TDS3014 DPO scope at my job, and it is an amazing tool.
For my personal use, i can't buy a 5k$ scope, so i have bought RIGOL scope 2 years ago, a DS1022CD.It is a 2 analog channels 25MHz 400Ms/s, with 16 channels logic analyzer. I had payed it about 500$.
It is a very good value for money !
I highly recommend their products.
(After that, i have also bought the generator and multimeter from Rigol, also
very good products !).
Algar_emi, i really think that "PropScope" is too expensive for what is that.
If you look also for a standalone scope, and if the price is an issue, maybe this product can interest you :

5 years ago I got a TiePie HS3-5 USB scope for somewhere around $600. It's not bad for audio. I do wish it had better than 16-bit resolution for the spectrum analyzer as I can't dip below -70 dBv and still keep the fundumental from clipping.
I'm of the personal opinion it has nothing to do with the samples per sec, but the resolution.
