Which do you want??
Do you want an official "Roll" bar,that will protect you in a rollover,or just a "light bar" to put off road lights on??...
If all you want is a light bar,with a little added protection,you could make your own fairly easy--I made several from galvanized electrical conduit from Home Depot--they have pre-bent elbows,and its not hard to "splice" them together using a short peice of smaller pipe or tubing that slips inside the conduit and welding them together...
One such bar I made for a freind did get "stress tested" when he rolled his K10 over in a sandpit one night...despite the fact it was not a "roll bar" by any means,it did hold up rather well,and kept his cab from crushing in too badly!--cant say the same for his KC daylighters though..

--you could use schedule 40 or 80 plumbing pipe for added strength,but you would have to find someone to bend it for you...some guys use regular exhaust pipe and elbows to make light bars...cheap and easy to make...why pay big bucks for the same thing you can make yourself in a few hours??...(unless you cant weld,dont have a welder,etc--then nevermind this post!
