Viesturs, if the logic analyser is a requirement, then something like the Bitscope that I use might be an option. It is a cute little box which needs an ethernet connection to my PC to work and display. It runs on linux, so TVTMAAOS isn't a problem here. BUT, the standalone oscilloscope which Gene linked to in the oscilloscope thread just a few weeks ago is cheaper and much easier to get down the stairs and into the workshop. Just no logic analyser. I did use the 8 channel logic analyser to debug a bunch of control signals I was bit-banging out of an ATmega328p, when my home baked LCD driver did mysterious things. The two 100 MS/s analogue channels would have got me there eventually, I expect, but the logic analyser put me in the fast lane. (Note: The Hantek only has half that sampling rate, but it is cheaper.) With a laptop instead of my bulky desktop, the package would fit in a moderately capacious laptop bag. It is some years since I bought the Bitscope, and it was significantly dearer then than the current crop of naked boards. But it does come in a thick extruded Al case. If you do buy one of the small units, don't forget to buy at least one high voltage x10 probe, preferably two. The ADC front end on the Bitscope won't take more than 63v, but that's 630v with the x10 probe, if the probe spec is up to it.
