Sucks to hear that Relaxer. Hope your home insurance takes care of some of the replacement bike expense. Stick w/ krypto/abus/granit chains and locks plus a mini-U to lock the wheel to the frame. You can leave the chain where you work if you don't want to carry it all the time. Also, CigTech did a review of the GMC Denali so check it out if you just want a cheap commuter bike to tide you over.
