I've heard a few horror stories about sealskinz products (and not just about the price!).
I swear by the British Army Soldier 95 gloves. Fair quality leather outer with thinsulate and goretex inner. I've had one pair for 4 or 5 years and in that time I've worn them doing 80 on the bike in the winter, out on the Brecon Beacons in the driving rain, absailing over 100 feet off Dinas Rock in the Neath valley and digging my way through brambles looking for a misper. All in all the best value £10 (thank you eBay) I've spent.
