I had a bad experience with the Jet 10" jointer planer combo unit. It was on sale at Woodcraft and, with a small shop and thought it would be great to have a combo unit. Assembly was simple but, as I put it together I wondered whether something so light would work well. It didn't. I was never able to align the tables and, if they're not perfect as milled, it may not be possible. The motor was not very strong and bogged down with very small cuts in 6" pine. I didn't even try maple.
After some negotiation with my local Woodcraft store they took it back for a store credit. Last time I was there it still hadn't been sold.
I currently have a Ridgid thickness planer in my garage (because I don't use it that often). I've been looking at the Grizzly jointer because they can be had with a spiral cutter head for a reasonable price and seem to have decent reviews. I would love the 8 inch version but wonder if I really have the room in my shop - so it will be with keen interest that I will follow your decision and comments from others.
