However, I tried them out and didn't find them that great, you can only see the very basics of the signal.

I ended up buying the LCD Scope from Seeed Studio. I bought the $49 assembled version, but you can get the kit for $33 if you are willing to build it yourself. Link is:

Quite impressed with it, and it's well worth the price. It's made a lot of projects much easier!

They've also got a new one which looks good, but I haven't used it so can't recommend it:
