I've not tried either of the jointers (mine is a Delta), but I have a Grizzly table saw and sander and they are both fine tools. I don't know what kind of bows you're planning, but you may find that a good table saw and thickness sander may be all you need. For thin lams, the jointer can do one side (obviously) but the planer can't do the other. If your table saw make good square cuts, the sander will size the lams. You can also cut the lams on a band saw (having jointed one edge first) then sand, joint the block again, band saw, and sand, until you have all your lams. I don't know if band sawing and jointing saves wood over table sawing. Of course with a better band saw than I have, you can probably skip the jointing. As for riser blocks, you could also get away with table saw and sander. DON'T FORGET DUST COLLECTION if you get a sander.
