I'm going to answer my own question: Rondo Music. They sell a LH Douglas Peragros: 24" scale on a full size body with 1+ 5/8" nut. It'll need upgrades, but for $99 I've finally got a starting point.

Is anybody making 24" scale in left hand? I was excited to learn about those Ibanez Omar Rodriguez, but the only LH I saw were in the UK - nothing it seems for the colonials.

Hope you guys can point me in the right direction.

Thanks.
