A third option besides MEE and Curtis is the Sleekline Enclosure, I think they're about the same price as a Curtis Cab, which I believe is about $3,000 installed. If you're also trying to avoid The Villages Golf Cars, the Villages Discount Golf Car store on 466 just east of Morse has a big ad in the Sunday paper today that they are now installing Sleekline enclosures.
