unless you want the satisfaction of actually doing it yourself, I would recommend buying the smittybilt kit, i got mine from Bronco Hut, but Jeffs and WH sells it too. You can still say that you built it because some trimming and welding is required, but it will save you a lot of time and I found it saved me some $ too. It says that it is not a 'roll bar' for liability reasons, but I have talked to people at Bronco Hut who have rolled theirs (reportedly 6 times). It is certainly a good place to start, you can add to it for strength if needed. If you choose to buy your own tubing, get DOM (drawn over mandrel) instead of rolled tubing- the strength difference is worth the $.
