definately buying new....I did a bit of research on the web too, and it seems you need an audio input and output on the laptop for recording and you treat the computer like a tape deck. You need some easily found software too. The prob is that laptops dont come with audio inputs , but you can buy adapters using a usb port....
Prices have come way down and a decent laptop with a pentium processor with 512 memmory is about 1g....groovin to Ivy now ...much diferent then blind faith but good to work to,.... man do I need some booze.....
