Not to offend anyone who owns one, but I don't really see what's special about them, or what makes them extra desirable : it's a non-Guild body shape, doesn't look like any Starfire before or after it, and it has Gibson type pickups. Might be a very decent ES-335 type guitar, but I'd rather have a Starfire or an ES-335, and this is kind of neither. Then again, I could see how that very thing could be the attraction to some people.
I always thought the fifties pickguard looked wonky on the SF body.
