Mike I have the early version of the G0733 and it has given me good service. It came with a few aww chit things but they are easy to correct. As far as I can tell the only difference between the G0733 and G0698 is the color. I have had mine going on two years. I do a lot of turning, check out my web site, Steercreekwood.com.
The problems I refer to are connecting aftermarket toolrest and chucks, the work around is simple and quick.
I'm not saying that the Jet 1642 isn't a great machine but for the money the Grizzly will do what the Jet will and more.
