Bill makes some very valid points, especially about the differences of opinion based on what each individual is comfortable with, and how they currently perform. Also as Billl said, different venues, different expectations.
A friend of mine recently bought a guitar synth (sorry I don't know the name) which follows his chord playing and adds bass and drums, and can change lead 'voices' to whatever instrument he wants for solos ... Have you thought about anything like that" ... This way all the audience sees is your guitar and you can have as little (bass & drums only) or as much (full band) accompaniment as you want....
