Hi. I am an older newbie that can use some help choosing a cyclocross bike. I having been riding to work out and commute on the road with a very heavy full suspension bike -- it's killing me. So I am about to buy a cyclocross that I will use for the same uses, plus maybe ride with a road club every once in a while. I will probably never do a cyclocross race due to a bad lower back (why I originally bought the full suspension), but in case this is a bad idea, I am also trying to take resale value into account along with a ride my back can handle. These three new 2009 "leftovers" are about $1100-$1200 -- any advice is really appreciated:

• Fuji Cross Pro Cyclocross (Shimano Ultegra)
• Cannondale Cyclocross 5 aka "CX9" (Shimano 105)
• GT GTR Type CX (SRAM Rival)

Once again, thank you in advance.
