I was going to say lucky you, but I don't think luck has a lot to do with it. I've never used one, but they are reportedly the bee's knees. And not easy to find.

I have been thinking about making Phillip Morley's mortiser.  It looks like a like a good design and easy to use.  You can get it in flat pak and do just the assemble or buy the plans which is a lot cheaper.

I didn't know what that was, so I looked it up.  I don't have a place for loose tenons in my work.  I have two mortising machines, but they're too much trouble to set up for a small number of mortises.  Usually, if I have just a few, I'll just chop them by hand.  I mostly wanted this thing because I didn't have one, but I'm sure I'll find a use for it.  I recently bought the small Makita router kit, with plunge base, so think that will come in handy with this, and also have a Microfence coming to fit that little router.

Those are supposed to be fantastic.  No telling what that would have sold for on Ebay.  A lot more than $25, I'd bet my lunch on it.

Edit to add photo...case and point, lol.

I bought one of these at an estate sale last sumer.  I think I paid $20.
