Best Buy in a Rear wheel
 

Hi I am in the market for a "best buy" of a rear wheel for my 2003 Gary Fisher Marlin. I broke the OEM one, replaced it with a cheap Mavic one with LX hub, now it is broken. I ride this bike in terrain that
it doesn't like trying to keep up with a buddy who had a 2000 full suspension bike. Any ideas with the emphasis on the "best buy" part?;)

It would help to know what mavic you broke, then we can offer a "best" buy that would break under your riding.
