i got the belt from sunset, with 6 sprkplugs and belt they charged me $42 i believe, $8 for shipping.
changing it out was a freeze, actual swap takes like 5 mins, once i got the cover open from the inside i figured out that i dont have a wrench that is big enoug (pepboys, napa,home depot, or lowes didnt have the size available), i found it at autozone for $8.
heres a pic of my 2.5 change, and what the belt looked like at exactly 60k (well, 60,032 hehe to be specific)
here is the before
and after, you can clearly see the cracks on it
