Bread board quality

I don't think I've ever had a breadboard so bad the holes were not drilled out. As I mentioned above, the 8-10 dollar range at digikey like the adafruit one. I use them for exactly the purpose you are thinking. Low speed, and know that there will be parasitic C and a few ohms of R likely as well on the connection. BB's are great for what they can do, awful for precision/high freq.
 
You can get a variety of breadboards from Busboard systems. Here is one with the power rails in center instead of on the sides.

The ones with copper are a good quality with an anti-tarnish coating

I find these boards are good for Arduino or digital projects but not so good for analogue because of form-factor variance, Opamp circuits tend to oscillate.

I was wondering how people are using their boards so I asked the support guy to recommend some software tools. He had no answer for that. I have been using veroroute. It has a good autorouter.

I tried various Amazon prototype boards for soldering. Some have plated-thru holes which limits solder blobs while making good connections. However, I find it too tedious so I am learning KiCad.
