Thanks everyone for all the info. I am a huge diesel fan, but I am looking at used units and would prefer to keep the price low and I also like to do my own maintenance - which is much easier on a gas unit.
Anyone have a small unit for sale? I am open to wheeled or tracked units now, I have learned enough to know that a wheeled unit would suit my needs now, although I see the need for a track unit in the future.
One other question - for you guys who run Kanga - where do you get parts/service?
