Recommend a method of getting analog into my PC

I am going to start ripping vinyl into WMA files for my dad (I stole his collection). Lossless is what I am going to use.

I have a nice vinyl front end with tube phono stage. I need to know what software and hardware I will need to make this happen.

I don't think the sound quality will be what I need through a sound card. A usb device would be absolutely ideal. I would like to spend under 500 bucks.

Any suggestions?

Thanks - Evan

Sorry if this seems like a newb topic, but I have done alot of searching and had less luck then I thought I would.
