PC Video Editing Software

Does anyone have any experience with any video editing software out there??
Im looking for a program that can put together a nice ~20m clip with tons of transitions and effects and being able to add MULTIPLE audio tracks......not just 1 or 2 tracks......
ive been looking into Adobe Premiere 6.5 but im not sure if that has the features im looking for. I also have heard its rather unstable at times.......is that due to software or hardware? *shrug* The program itself is like $600 through Adobe (so ive read) but ive found it bundled with a firewire card and extras for roughly $250.....

anyway.......any ideas? suggestions?

Personally I wouldn't bother with adobe premiere. Take a look over at www.pinnaclesys.com as you'll find Edition 5 a very tough product to beat, and its around the same price as premiere. It has unlimited audio tracks capability plus hardware video acceleration support. Nothing else comes close. There are also various lower cost alternatives, so take a look around that site.
