Many manufacturers have gotten away from the Unified Rear Triangle design, but hey schwinn has also gotten away from NOT being sold at Toys R' Us too. Overall, for 3-4 hundred dollars, I think that schwinn is a decent buy, just make sure that the wheels, pivots and fork are in good shape.
Also do NOT count on any kind of warantee from schwinn. Like I implied earlier, both Schwinn and GT are owned by Pacific cycles now, warantee coverage of past product is minimal if at all. This past week I have worked on 5 schwinns that were built by some untrained jackoff at Toys R' Us, and what a headache.
And for those doubting full suspension, the weight has come down and the efficiency has gone up. Systems like the Giant NRS, the Specialized Epic, Trek's Fuel, and others like them virtually eliminate the problems of pedal bob, and the frames with rear shock only weigh about 2 lbs more than a comparable hardtail.
I don't know about you, but I have at least 10 lbs of weight I need to lose off my body before I start worrying too much about a 2lb difference in the weight of my bike.
