Last summer, I was in the same boat. The Motobecane MTN bikes looked to be a good value. From what I understand the guy who resurrected the defunct name started getting decent frames and putting decent parts on them. When I was shopping I noticed that there weren't many complaints about them but there wasn't anyone bragging about them either.
I ended up considering Giant, Gary Fisher, Trek and Specialized. I bought a Hardrock because I liked the feel of it. I have also grown to like the funny shaped tubing. So I actually like the look more. I changed out the deraileurs (to XT and LX). Even though the stock ones worked fine, I like the new ones better.
Don't forget to make a list of accessories such as spare tubes, pump, patch kit, multi tool, saddle pouch, bar ends, lights, blinkies and etc. Often dealers are unable to discount bikes (due to distributor contracts) except for model year changeovers but will give enormous discounts on accessories in order to make the sale.
