I'm about to buy my first mountain bike (just getting in to the sport) and am choosing between a 2007 (used, banged up but good mechanical condition) Gary Fisher Hoo Koo E Koo, or a brand new 2009 GTw Avalanche 2.0 Disc.

I know the HKEK is a better all-around bike... but it's used & slightly abused. I did have a mechanic check it out & it's in good condition, but will need tires & the a piece replaced ($60).

I'm tempted to get the shiny new GT... but want opinions... is the KHEK, used, still a better bike than the GT?

Both are $450...

thoughts? opinions? advice?

THANKS!
