Hi,
You can check the Anthem 1, trek fuel ex 5 or 7, specialized stumpjumper comp, santa cruz tallboy and cannondale too. Like i said before, look for Deore components or better (altus<<alivio<deore<slx<xt…..) or sram x5 or better. As for forks and shox, Fox and Rockshox are what you are looking for. Rockshox products are usually less expensive than Fox, and i never had trouble with those i owned. The downside of mid level full sus bike, however, is that they cost much more. Bikes companis rose their prices alot in the lasr years.
Look for reviews on this site and on mtbr.com
It can take alot of searching before you make your mind, so be prepared ! Keep us updated too and we will give you more advices.
