So ask your coach what he'd recommend that's in your price range and go test it. You just might be astonished at the difference. Or not notice any. Why are you asking us before already having done that? See if the shop will allow you to take the bike to your coach's recommended fitter too, just to see. Do something. And yeah, get the PM with the bike, if you buy a bike, part of the package. Ask the shop. Might make a difference as to which bike.
I'd ridden steel and alu when I bought my carbon bike, and I was astonished. Just sayin'.
