sound card recommends for noob?

Anybody have a sound card recommend for a noob? I’m running Linux, Ubuntu 10.04 64bit. I’m new to Ardour and Linux and have hit the limits of my on-board sound chip. I read in a different post a recommend for the M-Audio Delta 1010, but that’s more than I’m ready to spend on a first card. Thoughts on the Delta 44 or 66? I don’t have any specific uses in mind yet, but would like as much flexibility as possible.
