The 733 is a 18×47, where the G0838 is a 16×24.
I have a couple friends who have the 733. Both talk highly of it.
I bought a Jet 16×42 before I knew anything about the Grizzly 733.
While my jet is fine. I would have saved $550, and got a little more lathe with the 733.
I have used a couple short bed lathes, and am not impressed with them. I prefer the longer bed. I don’t do a lot of spindle work. But it is nice to have when you need it. and it is nice to be able to get the tail stock out of the way without needing to take it off all together. The Grizzly’s tail stock is much heavier than your Rikon.
I find it a pain to take it off to get it out of the way. But an extra $500 for the 733 is a lot if you don’t ever turn spindles. Just my 2 cents. Your Rikon is a nice lathe. And the G0838 is too, but going up to the G0733 would truly compliment it.
