Just beware that most if not all shops now require you to have completed a "dry suit specialty" course or they won't rent you a suit. If you go the dry suit route, better off to buy one.
When I got my first dry suit, the course consisted of a couple of dives with the shop owner to ensure that I was comfortable in the suit, and was able to overcome any issues - the most common being air in the legs causing you to come to the surface inverted
