Once again, thank you all for your replies. I can see your point of shortlisting a number of machines, going into used machines etc. I am totally ignorant of this hobby but would like to learn ( what's a DMD?) As I live on the north coast, nsw, there are very few machines available to play and I don't know of any servicing facilities in this area.
There are so many machines to choose from it is quite overwhelming. Guess I'll have to go to the cities to find out more.
Thank you again for your time. Mike
