[linux-audio-user] sub $200 sound card recommendations

Hello, I'm hoping to spend no more than $200 to get a sound card that'll do everything I need from it. It will function as the center of the sound system in my art gallery; I'd like to connect it to a mixer via RCA. 2 output channels + headphone monitor would be ideal, although I could live with just two of the three. I do not need digital, and I do not need surround, although neither would hurt. I do like the idea of an external interface but that is not necessary. I'm running Ubuntu 5.4, 2.6 kernel, etc etc. I don't really have a lot of time to spend futzing with compiling & recompiling drivers; I'd like something that is easily (& well) supported by ALSA or some other alternative. I'd read a lot of good things about the M-Audio cards -- which one if so? Or would you spring for one of the SB Audigies? Or other? Thanks Reuben
