Depending on what connections and features you might want, there are several choices.
M-Audio makes decent stuff for the money. There a couple to choose from between $100 and $200. I use one of their cards based off the delta 66 sound card, but I write music so you might not need all the features. E-mu can make decent stuff too. They were bought out by soundblaster a few years ago, but they left them alone mostly.
If you use a laptop or want to be portable they make usb or firewire interfaces that would work. Don't know what you want the card to do. Digidesign even makes a flash drive size interface that has a 1/8" headphone out.
