Lane - I am about 6-9 months ahead of you on research - you have missed what I consider one of the best values out there - take a look at the deluxe pallet car from Unique. It is incredible value for $23k. The as-is finish on this car is so good you can drive it for a year before painting it. Powder coated frame, Wilwood brakes, IRS, etc, etc. - this car is the real deal. Plus, the Weavers have an impecible reputation - real nice people. I strongly suggest, being as you are in SC, that you pop over and visit them. If you are the engineer-type, you will sell yourself on it.
My budget allows me to stretch a few $$ beyond the limit you gave, so I am going ERA, but, it wasn't an easy decision. The Unique is real nice - especially if you like the 289FIA.
Good luck, luke-44
