Knowing a few "in the trade", as it were, I suspect that another reason for the lack of a forum
etc. could be that those old [censored] are too mean to share their (what to their minds is) hard-won knowledge!

Why not go ahead and make your posts here, Dave? Or, if you want a bit more confidentially, we may be in a position to "consult" on the matters to which you allude. In fact, I know some folk who would be happy to come out to Oz and help y'all set it up!

PS: an old Mate of mine has built up a dental and x-ray servicing business all across the UK over the last twenty years or so. For a few years now he has wanted to retire (and so he should), but has been unable to find the "right" buyer for his business. If anyone wants to think about having a go (possibly with others, such as myself, giving assistance as necessary), feel free to get in touch. But be clear, I'm thinking in terms of a "younger man" (
ie, someone who can expect to put in twenty years or so at it).
