If building it yourself is the top priority, FFR is a good choice. There are a myriad of other factors to consider, too. Here are a few other companies to check out:
B&B
Backdraft Racing
Carcepts
Hunter's
Plus a few more a little higher up the food chain:
Lone Star
Shell Valley
Unique
These are only a sampling of all the choices. Even if you're not interested in a manufacturer, for whatever reason, you can still learn something from them. My advice is to spend enough time researching until you understand all the tradeoffs and make the most educated choice you can. In my case this process took more than a year.
