I'd love to get The Metabaron's in oversize but I missed that boat and the prices are just too steep for any book that's just a reprint of previously published material.
The lowest print run I think I've seen for Humanoids for the OHC version of a release is 500 . Legend of the Scarlet Blades was only 500 published 9 months ago and is still available cheaply.
Those reprints of The Incal and Before the Incal are already available to preorder from TFAW at $36 each for a September 24 release. My experience with TFAW is they package well and have reasonable shipping costs (even overseas). They also have "insurance" with each purchase to protect from price drops up to 30 days after purchase. Got half my money back with that once.
