Well, I pulled the trigger on a G0634Z jointer/planer yesterday, got an e-mail saying it would be here middle of next week, when I'm in D.C. on business. Called the freight company and told them my schedule, and they said no problem.
Hope it's all I want it to be. It will free up a 3' x 8' assembly bench that has been used as the infeed/outfeed for my current planer. I can now use the bench for assembly space, which is badly needed. I'll be selling the G0490 8" jointer, and giving my son the planer. I was pretty sure I wanted the combination for space and jointing widths, but read some posts last month that made me very nervous about spiral head inserts (on several different manufacturer's machines) and problems with heads.
Had the president of Grizzly address my concerns a couple weeks ago, here, so we'll see how I'm feeling about it in a couple weeks or so.
