Malibugary, if you are only going to dive a dry suit four times a year, would you consider just upping your wetsuit insulation? Dry suits are really something that goes better with some skill, and you develop skill by practice. I can't imagine doing most of my diving wet, and just switching to a dry suit a few times a year -- I'd be too frustrated to enjoy myself.
But if you are going to buy a suit, the Fusion is a very reasonable mid-priced, highly durable suit. It comes with three skins, the Sport, Tech and Bullet. The Sport skin is Lycra, and allows incredible flexibility, but you cannot put pockets on it. The Tech skin is a mixture of thin neoprene and Lycra, and you can put pockets on it, but it definitely is heavier, slower to dry, and reduces flexibility. The Bullet skin is neoprene, and is more durable, but much heavier, the slowest to dry, the most annoying to care for, and it dives like any other dry suit in terms of mobility. When I use a Fusion, I use the Sport skin with a pair of pocket shorts over it, because the pockets are better, and the suit retains the mobility and lightness that make it so attractive.
