well define a tight budget, I dont have any to sell im just trying to help you out. For example i just bought a pair of last years Moment Comi's for $410 shipped, that was a good deal, and there alot of those on TGR forums, and on here from time to time. but honsetly if you want to get a nice pow ski with some bindings, your probably looking at around $400-600 bucks, my buddy of mine paid close to $900 for his ARG's that he bought for around $450 i think and then had them remounted with better, brand new bindings. so yeah that puts into perspective of how much a pow ski costs, so its awesome having a pow ski, its just very hard to find a good pair for cheap. so anyway thats my two cents.
kinda short for the lengths you mentioned but worth a shot. 175 jj's in your price range and in great condition. if they're too short, sorry for crowding your thread.
