Jim, it's not the quality of the build but the quality of the bike! A walmart mongoose is a cheaply made bike with inferior components. A REAL mongoose has good quality parts and is better designed and costs much more. The bike in the pic he posted probably costs well over $2,000, while a *cough* full suspension walmart bike is probably well under $200. You could probably buy 3 "expensive" walmart bikes for what the shock costs on that high end mongoose 
yeah the way i break stuff, multiple cheapos would last me longer..... beaten then put away wet
i cant find cheapos though.... i need the tall sized bikes, and they just dont make the cheapos in that size, like a 21" frame is what i need....
