I'm surprised those Craft gloves didn't work (I own the full fingered pair and they've worked great for me), but it sounds like you have hands that are strongly on the cold side.
Those REI gloves looked interesting.
45nrth sells some warm bike specific gloves...I'm actually a little confused, I know they were also selling a mitt and warmer gloves, but right now this is the warmest glove on their website (They say 0-15f):

I see others have already mentioned pogies if you need the ultimate in hand warmth. I know they vary in warmth, the ones listed on this page under "Expedition Pogies from Epic Designs" :
Winter Cycling Gloves, Lobster Gloves, and Bike Pogies Buying Guide - Bloom Bike Shop
Are ones I've seen mentioned before for being over the top warm. Also expensive though. Good luck. :-)
