Well I think you will have to check shops and decide what components you need. LX components are cheap and long lasting and easily replaceable. You could get a great lightweight durable frame with parts and a high end fork.

Giant, Specialized, Kona, trek etc...all make similar quality xc ht frames. The geometries are all very similar as well. Since frame is out look for a deal around you with high end components.

With 1000 american you have enough to get a good bike with above average components ...
