Just a thought, are you moving to Boulder for this job? It's a bike town. If you can get by on a cheap old klunker for a while, you could do some leisurely "shopping" by looking at what sorts of bikes are being used, and think about which features you'd like to have on your new bike.

And the klunker will always serve you later if you want to take it somewhere with minimal risk of it getting stolen, or it might become your winter bike.
