I also really enjoy playing with a slide. I like to use a lot of reverb and/or delay to acheive some really spacey sounds. I want to get a crappy guitar and set it up specifically for slide: raise the strings, pickups, etc. That way I could play better . . . :-) [w/o buzzing as much]
I am glad to see someone else still enjoys slide guitar.

Just my 2cents ;-)
