There's also an inexpensive suit on this sites' classifieds
FWIW, don't skimp on a suit. The fact that you'll only race 3-4 times per year might reduce the chances of you being in a fire. However, if you are, the fire won't care whether it's your first time or your hundredth.
The fire also won't burn cooler just because you are a club racer or an open track participant. If anything, we have fewer corner workers, less prepared emergency workers and are farther from trauma care should we need it than any pro.
OMP, stand21, momo, sparco, simpson, bell-pyrotect, design500 all make good quality suits.
RacerWholesale's auto pros offer good protection for little cost, I know 2 people who bought these suits and bought another within 2 years of racing due to stitching failures.
