Samurai,
I highly recommend Sparco suits from Sube Sports
www.subesports.com
I tried on a million other brand suits, and most felt like burlap pajamas or a heavy jogging suit. The Sparco suit felt so comfortable, I didn't care how much it cost, I wanted it. Just drive down there, try one on, and you'll see what I mean. They have very good economical suits with the high fire ratings standard (SFI-5). You're looking at $450-500. Ideally, you want lightest weight suit with highest fire rating. Other less expensive brands may use Proban or multiple layers to get the higher fire rating, then they end up feeling like a fireman jumpsuit.
Look at the Sparco Sprint 5 or Sparco Fashion 5. They are the same materials as the $1000 suits, but they are stitched more economically and usually in 1 color. They carry custom tailored and "off-the-rack" sizes. I bought "off-the-rack" because it fit great, and it was a couple of bucks less than custom tailored.
They can also offer a package deal if you get the helmet, gloves and shoes there too. I like the Bell Sport 2 helmet.
