n-Track is great because of its price. You really can't beat it...nothing comes even remotely close.
I've been using n-Track for about a year now and it seldom lets me down. It runs best on NT4 or Win2000, and can really run like crap on 95/98. Be warned. Play with the demo for a good while and ask questions on the board over at fasoft.com.
I got a chance to play around with Sonic Foundry's Vegas recently and oooooooooooooooh man it's so much nicer than n-Track. Yeah they have similar features but Vegas is just so much nicer to use. BUT, there's a 500 dollar price difference!
n-Track is 35 bucks. If you're new to recording, start with n-Track. There's nothing better for the price.
