Steam. Works on Linux.

I’ve used them and can find a lot of stuff that isn’t available on the more open seas, but maintaining ratio is a big issue, not sure if it’s my setup or the tracker itself, so I can’t download as much as I want to.

Software wise, anything without a demo. The support from companies is dire at the best of times and if something doesn’t work on your system your screwed. In shops you can test the suitability of something by testing it (sitting on a couch, laying on a bed) but with software they take your money and run.

Also anything abandoned is fair game.
