Genie,

I checked with some of the local music stores in my area, describing your requirements, and they all advised that you should look into Vocalpro. According to them, the Vocalpro line is pretty decent, as far as karaokes go. The model that provides guitar input (also DVD, CD,etc.) is about the size of a small television set and can be carried with one hand. Only problem is, it's $499.99, tax not included. That price was quoted to me by Mars Music in Springfield, VA. They have a couple on clearance right now. One has a wireless mic and they've had some trouble getting it to function, which is probably why it's on clearance. Happy hunting.
