Well, the first thing I would ask is, what would you use it for? If you are doing shore dives with long surface swims, or diving where unexpected currents come up, or diving sites which sprawl and where you rarely get to see parts of the site because the distances are too great, then a scooter is a great tool.
The second thing is, do you know anybody else with a scooter? If you're the only one who has one, unless you're a habitual solo diver, you're going to be a bit out of luck for buddies. (Although a dive or two with a buddy that you let use the scooter for a couple minutes often ends up with more scooters in the community . . . they're like crack cocaine; one taste, and many people are lost.)
The third thing I'd say is, if you are going to get a scooter, take a scooter class. There is a lot to running the things, handling malfunctions, dive planning for dead scooters, keeping a buddy team together on scooters, etc. My husband took a class after we'd had our scooters for almost six months, and he learned a TON. I'm going to do the same thing, as soon as my schedule permits me to get into one.
