Hey Ho Denzel. There are quite a few Mark Munroe units in Melb and a few less in Sydney.
I think the unit it's self is great and I would suggest considering the the one display but three sensor model. It can do one if that is all you want/need and/or upgrade to two later or three.
Richard's from South Africa is a sweet unit and lends its self to a HDD conversion pretty easily. (got to know the right men)
Also a good simple installation is the KISS displays, small simple and ready to go.
Depending on how you intend to put the Sensors in the unit, T-pieces on the loop or P-ports in a lung etc,
http://www.tecme.de/zubehoer.htm will be able to help if you don't have access to a lathe or its operator.
Where are you living these days?
Anywhere close to Tubby? I am sure he can give you some to look at and help with a decision.
Welcome aboard, the ride is fun.
