For the money 1 GS/sec, 100 MHz BW ...could be handy...has limited voltage ranges & waveform samples...but the price is right. Wonder if it is any good?

After seeing some of the reviews...it seems to not really be able to get to 100MHz or 1 GS/sec!! ...maybe a hack will bring it up to full speed? Oh well...wait for round II
