I use an emu1212m. You can find this at musiciansfriend for around $199.00 I think.It has been a great soundcard, I set the latency to 5ms and it works great with my native instruments guitar combos software. Can't even tell your not using onboard effects. It has two 1/4" inputs as well as two 1/4' outs.As well as midi in and out. Great card for the price. However be aware that it requires 2 PCI slots, not 1 like alot of other soundcards.
Cheers
