I just met Jim Soloway at the NAMM show. He had one of his guitars on display and available to play at the Fuchs Amplification booth. We talked about them and I played it briefly. Jim is a talented Luthier. He mostly plays a 7 string himself, if I recall the conversation correctly. I'm sure his guitars would be beautiful for
slide, although not particularly my first choice.
I was into pretty guitars for a while, but came to the conclusion that I didn't really want to play anything that I couldn't ding, drop, sweat on or spill stuff over. But if you like websurfing for pretty guitars, Google any of these luthiers

I'm also fascinated by James Trussart's creations.
