Do you think they will ever come out with an aftermarket Domino? I don't know when Festool brought out the Domino. I do not intend to buy one but still, I have been wondering "When".
Lemmelo introduced the biscuit joiner. They went/go for Festool like prices.I don't know what the patent deal was but eventually everybody was making/selling then, even Ryobi and HF.Kind of like the Fein Oscillating Multi Tool. Original was kind of pricey. Once the patent expired everybody got into the game. Fein had to drop their price to stay competitive.
Tom someone posted on a thread about different types of joinery a few years ago a video of an amateur woodworker testing various joint types for strength. Although not a scientist in a testing lab, his methods were reasonably sound. He took either a hydraulic or pneumatic ram and attached a pressure gauge to it and then used to the ram to see how much pressure applied to the ram it took to destroy various joints. Obviously butt joints, biscuits, and pocket screws took the least pressure. But surprisingly, dowels were not very far behind M & T joints. I guess really not all that surprising since a dowel in two holes is for all practical purposes a type of floating M & T joint. If you approximate the amount of dowel to equal the size of tenon in a specific situation and use good wood for the dowel(s) then it probably won't make enough difference to matter. And it's much easier to use dowels than it is to make M & Ts. The trick with dowels is to precisely line up both holes and a good jig does that.One dowel is not going to hold up as well as a 2 inch long conventional M&T or a joint made with a Domino
