There's several options out there nowadays, and several have been listed above. I am obviously going to be a little bias to our own products... but if I were narrowing it down my choices would between Porterbuilt and No Limit.
Do some research on the products offered and companies producing them. Search the web and make a couple phone calls. Then make the best decision that suits you and your project goals based on the information you gathered.
In regards to track proven.... Curt at Hills Rod and Custom has our front system on his Blazer... it does alright!
