Hey guys, I've been reading this forum for a while now and I need some input. I've basically narrowed my choices down to a Trek 4300, Trek Gary Fisher Marlin, and the Specialized Rockhopper. I went to the LBS today to test ride the Rockhopper. I did not get a chance to ride them because I wanted to ride a 19" (I'm 5'-10) and they had to order one, so I'm going back on Friday to ride a 17" / 17.5" / 19". I plan on test riding the Trek and GF tomorrow. However, the LBS with the Specialized has a 2010 Comp @ $699 and a 2011 (regular) @ $629. The guy mentioned that they could make me a deal on the 2010 Comp if I was interested (he didn't say how much). From looking online, I can really only see that the major difference is the better front fork on the Comp. Is there any other real significant differences between the two other than the color schemes? What kind of discount should I be looking for in a two year old new bike? Thanks for any input.
