someone is selling a fk04 for $290 on these forums. i'd recommend this as it is also proven in mod if you want to move up...try and get it for $250. it's the old model anyway still excellent though. ask for pics of the cvd hub (these tend to warp severley. if they are warped very bad the bearing is almost impossible to remove) also get some pics of the rear diff outdrives (make sure these are not overly worn out. along with a pic of the belts. make sure they are not frayed or folding over.
