I need an exposure unit, located some where on the east coast, can pick up

i just recently bought most of the equipment i need and the only thing im missing is an exposure unit to complete the deal, i can pick it up and can afford to spend about $500, prob wont get me the most up to date unit, but as long as the vacuum works and provides good contact i will be happy.

thanks for any help.
