So last season I stripped the threads in my driveside arm. I have been looking for a replacement all winter but have come up with nothing.
So now I need to find a full set that will work. With the phasing out of all 7speed stuff, and a lot of 8speed. What will work? I would like to go with XTR stuff again... but I honestly don't have more than $100 to spend. Any other good brands I should look at?

I have a Truvativ Firex SL Crankset, and the thing works really nice. You would also have to get a Truvativ bottom bracket, but it is pretty torsionally stiff in the arms, and not a bad price. www.jensonusa.com has them for a good price.
Seven- and eight-speed systems generally use the same chains and chainrings. Since nine-speed chains are a bit narrower, one can generally use older chains with 9-speed rings.

I have no problems with my 9-speed XT crankset and 7-speed rear, and you should be able to pick up last years XT's for less than 100 bucks.
