Feedback need on buying a new Mtn Bike

[bparker]

I am on a budget here 500-1000.

Can anyone give me some good suggestions in regards to a dual shock system for a large guy 6'3 @ 250 lbs

these are the two I am currently looking at

input needed.

This one is at 1k and fits the bill.. any rider experience here?

and ok this one blows the budget but I might luck out on an offer as he has several. Might get it for a bit over 1k-1.3k me thinks...
