Space is somewhat limited in my basement shop and I need a jointer. I am seriously considering a jointer/planer combo unit. I have a grizzly band saw and have been very satisfied. I am looking at the 10" grizzly combo unit, but haven't seen a lot out there about this unit. It has a 2 knife cutter and there aren't comparable units to which I can compare it. I have heard raving reviews about the Hammer 10" combo unit, but wonder if the $$$$ is justified. I don't see many of either unit for sale used, so it makes me wonder if few are actually sold or do the units perform great (keeping people from selling them as used). Any thoughts?
