Sorry...forgot to mention one addition. They do have corner brackets for hanging bags. Basically, they install caddy corner (attaches to two walls, basically). That way, it takes up less space and theres no worrying about holes in the ceiling/the ceiling falling in on your head. Not to mention, you can just throw spackle over a hole on the wall, while its a lot harder to fix the ceiling.

I cant get a photo for you, cuz I'm at work, and my website selection is VERY limited here, but if you still havent found anything about it by the time I get home (appx 7:00am EST (-5 GMT)), I'll find one for ya.
