im using the digi001

if u search for it on ebay..u can get it for a pretty decent price.....thats the older version of pro tools..they now have the digi002 which is a lot more expensive........but...the 001 is really nice as well...serves as an external soundcard as well.......its the interface u have to buy......u either have to get the 001,002, or an mbox to run pro tools......
