Another one worth looking at is Goldwave - (
http://www.goldwave.com/ )again free to download and try, with very minor restrictions and when I bought it, it was $25 - I use it for transcribing my LP collection to CD, and in the past, recording to .WAV and MP3 from my KN6000 - It's the best 25 bucks I ever spent on software
Just had a look at their website - it's now $40 but I would still pay that for it!
