K2?

[Starscream]

I am in the market for a hard tail mountain bike and not really sure what would be a good bike for bike path/trail/recreational riding. The K2 ZED 2.0 & 3.0 caught my eye, and seem to me to be decent bikes for the money... However, I don't really know what I am talking about, so I am looking for some guidance on what some of you would recommend. I would prefer to keep it under $700.00 if possible. Durability is what I am most concerned with.

Any input is much appreciated!
