Don't forget the bitscope:
http://www.bitscope.com/USB or Ethernet. Dual/Quad oscilloscopes with logic analyzer and wave generator in one box. It's an open source design.
The Bitscope looks interesting, but I'm on a Mac and I don't think there is software that supports Mac.
Bitscope does support Windows and Linux. I remember having read about Mac support too but I'm not sure.
