Reagents and waste stream disposal costs are much too great to deal with unless you're going to utilize such a machine very often and have a steady stream of money coming in to pay for things. Acetonitrile, very-very-dry gas for flushing the reaction equipment and controlling valves (water looks like the hydroxyl on a nucleotide and terminates chain synthesis), and I haven't even got to the activation acid or a few other required items.

How I know? I have a synthesizer sitting unused for 2 years because I don't want to deal with all that annoyance (when all I want to do it is design and validation of genetic constructs).
