thing i never liked about newmac is the wood/oil are burned in a separate chamber, i like the oil in the same one as the wood to light the wood. but newmac has a pretty good name going for them too.
That is handy bit it causes all kinds of problems down the road. One of the biggest issues with a set up like that is that the oil burner nozzle will easily get plugged up with ash/creosote. etc not to mention the electrodes. I think this is why most manufacturers are going with the separate chamber.
