Nice Music Man!
I am also trying to get to a point where my needs are covered in as few guitars as possible. I've just about got it to that point, but I know I want a Sustainiac and I'm still missing a guitar with a FR trem. I'm planning on picking up a Schecter to cover those two needs. I usually just cut out and build whatever I need, but the parts list I had in mind for that particular build gets pretty close to what it costs for a similarly equipped new guitar.
I'm also looking at a Shuriken to fill the rest. After that, I'll reassess and sell off everything I'm not going to use. I have a bass and three self built customs that I'll not be parting with, but the rest will be sold off. I want to be under five guitars and two basses.
Between those, Guitar Rig, my Zoom multi, and a new Helix - I should be covered for a while.
