check jensonusa.com or pricepoint. best deal out there right now is the shimano LX crankset- $85. great deal, super durable and really cheap. was going to pick one up myself but something else fell into my lap. its not super bling, but will outlast most riding, is fairly light and shifts well. it will outlast that bike, and probably end up on other builds.

one thing to keep in mind is that a lot of cranksets do not include a bottom bracket. it can be an added expense.

That altus crankset isn't bad at all- but it does not include the octalink bottom bracket. add that in (another 25 to 35 bucks) and you are almost up to the LX.
