I have the 2012NB. I previously had a Triton thicknesser but the annoying snipe was wasting wood and I couldn't do anything about it. The Makita is beautifully built in comparison, and the very minor snipe, head lock, depth stop and adjustment are great features. The extraction hood has a 50mm exit but it works efficiently for me given that I don't normally get anywhere near 3mm maximum depth of cut. I've tested it at 3mm but only up to 120mm width on softwood. I'm not sure that the extraction hood could cope with the volume of waste from a heavy cut and a larger width board. Somehow I doubt it.
It costs a bit more, but the head lock and manufacturing quality makes up for it IMHO
