FatBoy I use Reaper, It's a trial version but you can use it as long as you want before buying it. http://www.cockos.com/reaper/
majestikc Reaper is really good, it's from the same guy who developed Winamp, it's very useful and has pretty much everything you need to get some good recordings done.There also used to be a program called N-Track, and then there's also Audacity.
