Try wetsuit warehouse, they have high tech suits, and sales all the time. I picked up a Quicksilver, 4:3, it is neoprene, so stretchy, doesn't affect skiing at all, and has a chest and back thermal patch, and glued and blind stich seams, and a flap behind the back zipper, all so less water gets in, and warmer with thermal patches. Best suit I ever owed. I think I paid about $150. Love it.
