[Cartman] Screw you guys... I"m going home...[Cartman]
I was just told by the doc that my back injury will make bike riding a very stupid thing to do for the foreseeable future. I might look into a recumbent though, as I understand they are very fast and put very little stress on the back. Hopefully it will also help strengthen the muscles back there.
Anyway I just had to sell my Trek last weekend...
I think K2's are pretty decent bikes. They seem to run from just a notch above Wal-mart crap to some pretty high end stuff. If nothing else their graphics look awesome!
In reply to the mountain bike guy, if you are planning to ride mostly on the road I would probably trade up for a serious hybrid, such as a Trek 7700FX or a real road bike. There is a new class of road bike out there with more upright easy riding geometry if you aren't fond of the flat out road bike riding style. A Trek 1200C is a good example. You will get much better on road performance with more sensible geometry, weight, and gearing, not to mention tires...
In a nutshell a road or hybrid bike will give you more miles covered for the energy you expend.
But in true ARFcomm fashion I would recommend you get both! Keep your MTB and get a dedicated road rig too! It sounds like you will be putting more than enough miles on your bike to justify the outlay of cash. And yes, buy as much bike as you can afford. You will enjoy it more and ride it more as a result.
