If you want a pre-bent one. The Autopower is nice. I have the "U-Weld" cage with the racing roll bar. You should be able to have someone put this in for you at a nominal fee. I welded mine in my self and it was very time consuming. The cutting and fish-mouthing took alot of time.

If you plan on racing, check the Rules of the sanctioning body on the types of cages you can use. Some allow for smaller tube than others and some require different cages based on the class you run in.
