Julia -
I am one of the people (or used to be) on the VISTA list.  I liked Vista
very much - used it for two years - before I moved on to a new museum.
It has the advantage of working on your PC, the responsiveness of the
company is great, and once all you material is on, its quite user friendly.
Rather than bore everyone with the details, why don't you give me a call.
