Go GT matey, I got an Avalanche 1.0 custom and it is the ducks nuts.
Keep your eye on Ebay for somebody elses machine with all the upgrades on, it's like motorbikes people buy all the go faster goodies but really can't use them to their full capabilities and get bored, sell it on and lose out big time on all the goodies.
I picked up my Gt with full XTR upgades, an $800 set of rims, Xt discs calipers and lever etc etc and had change out of $1000.
Estimated build cost around $3500- $4000
Never buy brand new, go for a high quality second hand that has been looked after, more for your money.
My 2c anyway.
