Right now i have a Sound Blaster 16 PCI card and i want to record all of my old LP's and tapes CDs. I would like to now what hardware/software i will need and your opinion about this. I read about the Sound Blaster Extidgy USB one, but thats a little expensive for me, how about the new Sound Blaster MP3+?

Although I've never used anything like this, it looks like what you are looking for, and it costs about $20. Look here. Again, I can't recommend it, it's just something I found on a Google search, and looks like just what you are looking for.

if you just want to copy audio cds to your computer then db power amp would be a wise choice
