My first mountain bike was a Trek 930... big mistake! I folded the frame in half (seriously)
I then picked up a Specialized Rockhopper. I had a blast on this bike. I taco'd a couple wheels, but the frame and front fork (early Manitou 3) held up great. It was stolen
The last bike I purchased was a Cannondale SuperV 700. The frame has held up fine, but when I bought the bike it had a lower spec component group... Shimano Alivio derailers and brakes, RockShock quadra5 fork, and Fox Vanilla rear shock.
I traded the Quadra 5 for a Manitou EFC. The Alivio stuff eventually was replaced with XTR goodies. I blew the valving out in the Vanilla shock and went with a Riesse (sp) rear shock. The wheels held up fine untill I went on a ride by Mt Rainier. (Suntop) rebuilt the front wheel, and added a Ringle superdooper bubba hub... no problems since. I added Magura Hydraulic brakes to keep my downhill endeavers under control... ... I still have the bike... . I am very happy with it.
I am partial to Cannondale, but I recomend that you stay away from the Headshock, and Lefty front forks... ... I just do not like the design, and it is too proprietary.
If you honestly just want a bike for 90% road time... . I would suggest the
F300 or
Jekyll400 When you feel the need to venture on to the nearest dirt path, either one should suit you well.
