A TS is on the horizon.

BTW, I didn't say I was ready to run out and buy a Domino, just that I
was going to learn a little more about them. I was serious though about
the biscuit cutter and a jigsaw (I didn't mention the latter).

Get the table saw immediately. Before anything else. You use it for dimensioning plywood and cutting solid wood. Table saw is used to cut everything.

Skip the jigsaw. Its inaccurate. Does not, cannot cut straight.

I have the DeWalt plate joiner. Its good. I think its the best plate joiner available. I use it for edge joining boards to form panels. Great for that. Also edge joins plywood.

But, if I did not have a plate joiner or the Domino, I would likely get just the Domino. It can do what the plate joiner does for me, edge join boards, and do much more.
