To be honest, the only buttons I ever really touch on the textronix are Timebase, Trigger position and aquisition mode (single, continous). Other than that, I don't really touch any other buttons on it.
The thing that I could really do with is being able to capture waveforms (screenshots) onto the PC, the tektronix can do this but it requires an plug in module which we don't have.
As you say, it's substantially cheaper than anything around it, even if only the basic oscilloscope functions work then it'd probably be a winner for me.
I keep looking at the bitscope year in year out, but everytime I look at it I just think "junk". Even doing "hobby" stuff at home, it'd be severely limiting.
It'll be interesting to hear your thoughts on it after a week or so of working with it.
