I have the seperate cab and head units of

and love them. Not sure of the total weight on it, but the cab is very easy to carry in my opinion. Hell of a lot easier than the Peavy 115S I used to lug around (or did it lug me around >.> )
I'll be honest, the sound is a lot better and louder than I would have expected for the price. I bought it mostly as a very small venue, personal monitor kinda rig. It turned out so well I've used it with no issues in larger theaters.
