A school of thought I tend to agree with is to avoid internal sound cards. Pick up a good external USB and/or Firewire interface. The Motu Ultralite Mk3 offers both and I've made absolutely excellent recordings with it. For 25 bucks, you'll be lucky to get what you pay for, unless you don't care about quality/fidelity/noise, specs, etc. Check the audio forum for add'l suggestions that may still offer good quality but are less expensive.
