The new Associated car (12R5...I wouldn't even consider one of the earlier cars unless it was damn cheap and budget was my 100% concern) appears to be a very good value and reasonably high quality. The BMI is INCREDIBLE quality, genuinely innovative product(s) (the guy who designs and manufactures them is a real 1/12 guy), unmatched customer support (Jason is online pretty much everyday and only a phone call or e-mail away to answer questions, etc). PLUS you support a 100% Made in America company when you buy BMI, not just another "we'll produce 'em in China so we can sell 'em cheaper" product.
Plus the BMI is every bit as good as you've heard. I've only heard mixed reviews on build quality and handling of the new Associated car and haven't had a chance to drive one myself. I have purchased and run two DB12R's and haven't been disappointed since making the change. Tweak-free and feels like it drives itself.
fwiw,
