Was the first place I looked and it was right on the home page. Would have been helpful if you mentioned if you needed 8 or 9 speed, and if you wanted road or mountain, if you have a preferred range for number of teeth. As well, your price range leaves a lot up to the imagination. I would consider that xt to be dirt cheap, I have no idea if you do as well.
jensonusa is great place to order from...i would suggest find the one u want and search the net for the best price then price match at jensonusa...here's some sites to help with the search for the best price once u have decided on the one u want
edit - found same one for $29.98 at pricepoint...if u like this cassette either get it from pricepoint or jensonusa (might still get the $5 gc)...both are good places o deal with
I am wondering if you can custom pick your cassette sprocket sizes. Like build a cassette with all the specific sized sprockets you want. (for a downhill mountain bike)
