Well, I'm a bass player, but its a guitar, and its electric, so I figured I'd throw in my 2 cents

I have a Peavy combo amp, not sure of the model.
My bass is a BC Rich NJ Beast, and I also have an Ibanez TR-70, an old Peavy that I dont remember the model of, and my newest investment is a Washburn AB-20 acoustic/electric.
As for storage, I keep my amp and the BC Rich at my guitarists house where we practice. He lives alone, and thus has no qualms about the living room being full of musical equipment, so we just leave it all set up unless we take it out somewhere. My Ibanez hangs by its chain (yes, it has a chain) from my curtain rod, and the Peavy is in a closet somewhere I think. The Washburn has its own stand

I think most musicians have a "jam room" or at least a corner of a room where they keep all their junk, so I don't know how well an all-in-one stand would do. I've seen stands that can hold 3-6 guitars, which seems like they would be pretty handy on stage or if your space is limited at home. One thing I thought would be pretty cool is a gun cabinet type stand for home. That way, you'd have room for cables, picks (though I dont use them), tuners, etc. and a door would keep the dust off of your guitars you don't use a lot. A lock would keep your babies safe from the kids too
