I know this might be out of your budget but have you looked at the MSO-19? http://linkinstruments.com/mso...
I designed this as the training tool for my high school FIRST Tech Challenge team the Landroids. They used it to develop various custom Arduino & AtTiny based sensor array for their award winning robots http://youtu.be/zRwOx2D7WCw . I packed enough features in the scope so the students can tackle FPGA based projects when the need arises. It was selected by NASA as the only oscilloscope on the ISS. And the best part is that it is designed and manufactured in NJ/PA to demonstrate that affordable manufacturing can still exist in the USA.
