What is the lowest-priced and best quality hardtail of the bikes that are listed below:

Ibex Alpine 650
Gary Fisher Tassajara Disc
Specialized Rockhopper Comp Disc
Giant Rainier
Kona Caldera
K2 Zed 4.0
Cannondale F5
GT Avalanche 2.0

Some things that are important to me are the longevity and quality of the frame, fork, and other main components that are not easily replacable.

Would it be worth getting an Ibex Ignition-3 Full Suspension instead? It is similarly priced and it is the only FS bike that I found under $1000 that even comes close to being quality. Any help would be appreciated!
