Personally I would save my dollars or look at Craigs list or some of the woodworking forums and buy a used Jet 6" or delta 6" for the same price as the HB.

But my whole issue was being able to do 6 1/2"-7" for body blanks. You can get some nice 6" jointers for reasonable prices, but the 8" get pricey.
Jointing the edge for glue up is not a problem for the 6". Now if you are trying to joint and square one surface to the other. then yes if you want to do boards larger than 6" wide you will need to go to the 8" or larger. If you have one good surface, then a good table saw, setup properly will do the jointed edge, then a properly setup rip fence to parallel the other edge. Then using, a planer to resurface the opposite face for thickness and parallel. I don't really use a jointer much as I really have no need for one. I recently sold mine. Unless you are buying rough or undimensioned wood, there are otherways to accomplish the tasks.
