Revolvers are not that bad and are a lot of fun to shoot.
They are not that much work to clean and certainly not dangerous as long as your not a complete idiot.

The best thing to do would be get along to a club and try a few different types of gun before you decide what to buy.

I have recently bought a single shot pistol and already have a revolver, they are very different things and each has it pro's and con's.
