I need to punch and kick something?

[Bob_Defly]

I'm looking to get some sort of punch/kick bag to improve my fitness. I do other training but always used to enjoy the punch-bag at my old gym, new one doesn't have one. I think there are basically four options:

Normal punch-bag (hanging)
Longer one for kicking too (hanging)
Some sort of water filled one (floor standing)
Or electronic thing like Slam-Man, might be more entertaining.

Any thoughts? I'd prefer not to make too much noise with it when the kids are asleep so chain hanging is probably out of the question (it will be in the garage attached to house). Has anyone used the Slam Man?
