It seems the more I research, the more confused I get...

I am 6'4" 225 lbs (34" inseam) and am currently riding a 1998 K2 Animal "Way Big" Frame Size (you can laugh - can't hear you). I bought the bike back in 1999 rode for a bit and stopped. I have recently gotten back into riding pretty seriously The bike is built like a brick sh*thouse, and weighs about as much. I like to ride fairly agrressively and would like to purchase a FS bike that will take abuse, climb well and take bumps and drops (nothing too serious) well. Can't really afford more than $1,500 - $2,000.

Your advice is MUCH appreciated!! Thanks in advance!
