        This is a problem we face daily also. There are many students and
researchers who need to use RP facilities. We currently have the Genisys and
FDM 1650. We use Genisys rather mercilessly and so far we have either done it
for free or for a Senior Design class do it for a flat fee (such as lab fee
usually picked up by the Dean). So far Genisys has been a good workhorse and we
are very happy with it.
