I bought a pair of waterproof gloves from Specialized which were waterproof but you could take out the liner and not have almost any insulation. Unfortunately they seem to have redesigned them and the new "Subzero" gloves are now mitten-style. :-(

The best looking gloves (from the pics) with a minimum of insulation that I've seen (online) are the Gore Bikewear Countdown gloves:

However, comments from the other people in this thread definitely still apply - if you're not also completely decked out in waterproof gear none of these options are good,. because water will just run down your arm into the glove. In this case, or if you just want something cheaper, I would go with the suggestion of Merino Wool gloves - not waterproof, but they keep your hands warm even when wet so they should be good for any riding above freezing.
