I got an oneill boost drysuit for Christmas and just tried it out yesterday in 50 degree water temp. It was awesome!!! I was not cold at all. If you don't have wetsuit gloves or socks then your hands and feet will still get cold, but my body was not cold at all. I have a wetsuit and used it in 60 degree water and while it made it more comfortable I couldn't wait to get pulled out of the water and dreaded falling. Yesterday, I was just floating in the water astonished by how I wasn't cold at all. If you have it in the budget to spend a little more, then the drysuit is absolutely the way to go (in my opinion).
