After quite a bit of research, I went with cryoed 5.29 Yukon gears from Longfield's (@$170 per set), Marlin's set up kit and Aussie Lockers (I believe I paid around $240 each). IMO, if you are looking for quality stuff, this is as "cheap" as you will find. As for the set up kit, no you don't "need" it, but if you want the gears to last, you are better off doing it right the first time.
