I've used the MAX7000 series devices previously - epm7032slc44 and=20 epm7128slc84. I had assumed that they were obsolete. I've only got=20 something like 15 pcs of the 7032 still in stock. Come to think of it, I think that I still have a few hundred ep600 or=20 ep610 devices hanging around. But they are only 16 macrocells - at=20 least 8 too few and way too much hassle to split among multiple packages. I just checked and they show that Digikey lists=20 the 7032 but with zero stock. Quest has them for $7 in the=20 quantities that I need. I'm still looking for other options but this is going to be my fallback pla= n.
