I have a cross check and LOVE it! If I were starting from scratch and buying a commuter, I would probably either buy a cross bike or a touring bike (also made to carry stuff, and has wider rims, etc.). I love my Trek 520.

Another bike to look at (since you have a Jamis dealer) is the Aurora. It's "MSRP" is $865, but you may be able to find one for less. Not sure if your preferred shop could get it or not. I do know that all shops can get Surly bikes, so that may be a consideration - the Long Haul Trucker is nice too

Good luck!
