Yep they're in the range but they blisteringly fast and your learning curve better be really steep otherwise it will be $$$$. He said entry level, I went out and bought a FD @ 20 years old. The first couple of weeks with it were nuts, it taught me to be smooth with my inputs to get the most out of it, but I was really lucky I didn't seriously mush it or someone while learning to do so. I believe the C5 to be in the same ballpark.
As for the miata being the answer, well I've seen fully built FM cars on the FM website for 6-7k. That's ALOT of car. A NA miata will teach more than punish especially with a good set of tires and suspension set up properly. So yes dollar per dollar the answer still is miata.
