If you believe that anything in politics can be "objective", I have a bridge to sell you.
Check out xprotolab (http://www.gabotronics.com/development-boards/xmega-xprotolab.htm) from Gabotronics. Not too fast or too easy to use but it is very capable and Gabo provides very good support. It is self-contained (small oled screen) but can also send info to PC over USB.
Also, the "arduino" teensy 3.1 could be used to make a USB-based scope for ca. $20 (plus some additional parts) and can have a lot of other cool uses too. Check it out: http://www.pjrc.com/teensy/tee... and http://forum.pjrc.com/threads/....
I've noticed several design suggestions in your code.
