Help me find a mountain bike

I did sit on a few and i noticed the fishers are set back more towards the back wheel, it felt better but i did like the look of the treks. The new flat black paint jobs were really cool, not that i care about paint but its a big plus. Anyway i want to go with new because i will be using my trusty credit card. Can anyone tell me what to avoid as far as parts? Is haro good cause i am looking at bicycles and more tonight and thye are a haro dealer.
