ISTR that somebody was asking about wall hangers suitable for an acoustic guitar. Well, I went out and bought a Hercules GSP39-WB hanger, which turned out to be perfect for both electric and acoustic guitars.
So now I have four of the buggers, and very nice they are too. They have auto-release arms, so when you rest the weight of the guitar on them the arms close in front of the neck and there's no chance of a guitar falling off the hanger. When you want to take a guitar down, you lift it slightly and the arms spring back out of the way and away you go. The hangers also swivel to accomodate different headstock shapes too.
Anyway, some pictures of them now they're up.

Aww, there's pretty:

Got mine from
soundslive.co.uk who I've used several times in the past and found they have really good service.
One word of warning. The screws and rawplugs that come with the hangers are ridiculously tiny, and so I used some longer, thicker screws and heavy duty rawplugs suitable for the plasterboard they're attached to.
