Being able to go from layout to printed paper so directly and viscerally is fantastic. If you've ever raged at InDesign or Microsoft Word, the physical embodiment of type, spacers, etc. feels like getting a glass of cold water in hell.
Of course it comes with its own tedium (can't Cmd + Z, can't just download new fonts, etc.), and I wouldn't advocate that anyone but specialty shops do a majority of their work on a letterpress; but having poured many frustrated hours into InDesign and its buggy features, it felt like a liberation to be able to control things physically.
To a degree, I feel like introduction to typography should be taught on a letterpress. You develop a much stronger feel for what's going on, and you physically grok what a baseline, em, en, etc. are. In my typography classes, students got confused by these notions because the definitions got muddied by the various software interpretation and implementations of it over the years (and the professor didn't do a great job at clearing it up either).
Having used the original thing first, the software implementations (and the liberties they took) became much easier to understand for me.
OTOH you might get lead poisoning. But I was probably in more danger from all the solvents we used back then.
Speaking of lead poisoning though, A pet peeve of mine is when people upcycle old california job cases in their homes. They look cool, but really should not be kept around in a home, especially one with kids. (https://www.google.com/search?q=california+job+case)
I'm not the expert on it, but I'm pretty sure SLA 3D printers are basically the same machine that printing folks get very excited about when referred to as "polymer plates".
They have an open house once or twice a year where you have the chance to run a print with their old flywheel platen press and see a demonstration of Linotype typesetting. They'll also show you around their refurbished Heidelbergs.
Here's a photo of Stan with the Challenge Gordon press (used to share a drink [too many] with him at the old James Joyce pub on Bloor where he was a regular when I was at U of T):
The Wayzgoose is real soon, actually! And beer/wine/hotdogs:
