Mark:
I just got back from Hot August Nights and spoke to Ron at SPF. What a nice guy. They make a nicely detailed car and I don't think you could go wrong with them. The workmanship was quite nice and I think it is the best car for the money at that price (or even lower).
ERA has been very nice to us over the years and they make an outstanding car as well. Can't say enough good things about them.
We have not really looked much at other cars. (Not being snooty, I just have never really had the chance to look at them. I would very much like to at some time though.)
