i picked up a hot/cold vacuum press for $200.
Good deal if it works. Did it come with a pump? Can save you a lot of headaches in the mounting department.
Forgot to mention there are some mounting boards like "Artcare Restore" with pre-applied dry mount stuff where a mounted print can be removed by heating it in a press like that, then peeling off the print while it's still warm. Supposedly meets archival standards for complete reversibility, but a true archivalist will probably scoff.
