I've got a pair of Ixon gloves (don't know the exact name of the pair I have), and they're seldom beaten by cold, but not so thick that they limit feel, IIRC I paid about £25 for them (although they're not armoured, if thats a deal-breaker). Them, plus heated grips FTW.
I have a pair of Spada gloves, but whilst warm, I don't rate them on the bike; they're to bulky, and they do limit feel.
