I occasionally a handful of various woodworkers blogs and one of those is John Economaki's from bridge city tools.
They recently announced another one-off hand plane (essentially a collectors item at a guess around $2500+):
Check out the pictures, I promise they're really cool (I'll wait).
Now here's the weird thing. I don't really want one, if someone gifted me one then sure it would have a nice place on the mantle, but no real interest in ever buying one.
But (and here's where the acquisitiveness kicks in) - how amazingly fun would it be to make something like that? Not to acquire the thing itself but to acquire the ability to create the thing.
Generally I find that when I see something interesting my first thought is very rarely "I want that" but more often "how is that made" and "how could I make something like that, or possible better".
Talking to my peers locally, this doesn't seem to be a common track for your mind to take, but I suspect that more people on here are on the same page? maybe?
