Jay, I didn't see your post until just now. Congratulations on your decision. I don't know about the Jet, but I'm pretty happy with my GO698, the predecessor to the 733. I mounted the tool basket outboard because it's pretty useless under the ways. I also got the outboard extension from Busy Bee. It comes with its own banjo, which has a swing arm, but it can't be used on the main ways. The outboard extension and banjo are much lighter duty than the rest of the GO698/733, which may be why Grizzly doesn't sell them. Between the tool basket on the headstock end and the outboard extension on the other, my lathe is well over eight feet long.
I'm surprised no one referred you to the Grizzly Green Monster Group. Most of these issues have been addressed. One thing that didn't come up here is that a lot of us have filed down the spindle slightly to get our chucks to seat fully. Some of us have had QC issues, but Grizzly has stepped up and taken care of us to most everyone's satisfaction. Tech support has been very helpful.
Hope you enjoy your purchase. +1 on the Wolverine/D-Way CBN/Woodcraft slow speed grinder combination.
