You sound alot like me when I started. I wanted to build, rather than buy. I wanted a high degree of accuracy - not one of those "loosley based on a cobra" types. And I wasn't looking to get into it on the cheap.
For me, Hurricane Motorsports fit the bill.

You will get lots of good input here.
Good Luck.
