what's wrong with your current frame?
if the answer is nothing... how much is it worth to you to buy a frame you want that fits you that has no problems, and how much can you make back by selling your current frameset? odds are you can't sell an hour for much. odds are you want a relatively expensive bike. i don't think a 722ts is going to be that much better than an hour. it's better, but not 2-300 dollars better. and by the time you're done with your upgrades, you'll have spent closer to twice the difference in values.
