Hey bro, for me personally I think anywhere between 250-300 is mid range.. Any higher is kind of pushing boundaries, that gets pretty expensive. That's where I draw the line, below 200 is well.. You get what you pay for, but there's some great shops around that range.. Hope this helps
Those pushing $400+ definitely not worth it for that price, my opinion and you really need to do your research to contemplate whether you'll get a bang for your buck there.
