Heated undergarment: golem or UTD

[Ianstephenzs]

I live in British Columbia and dive a lot 3 to 4 times a week but I have hit my limit. Its the cold after 40 min I still have half a tank but I am freezing. So I think I am going to have to invest in a heated undergarment. All i could find was the golem Q-Vest and the UTD Expedition Drysuit Heating System. (halcyon is to expensive) I was wondering what your experience was with these systems and what you would recommend.
Thanks Ian
