My Jamis Aurora was well under $1k and has everything you're talking about. I also clock 100 miles a week commuting and it's treated me very well. After a lot of research, test riding competing bikes (though not a Volpe) and gabbing here on the forums I ended up ordering one without having ridden it first, which I was a bit hesitant about but the shop I ordered from a) only required me to put down a portion and b) would have applied it to a different bike if I didn't end up wanting the Jamis -- which I did.
