I've had my delta 1010LT in my home pc for some time... I don't recall any problems, but I haven't done any recording at home. Yesterday I got myself the audiophile, because I need something for low-latency midi. Only problem is that the gnome volume control is completely confused, but it works. I've done some recording with Jack, and the latency with synthesizers isn't noticeable.
Although you didn't ask for it: I think that reaper running in wine
(with wineasio) is currently your best option. It really works flawless, even with midi. + you don't need to mess around with FST to run VST and VSTi's.
