Earlier quoted context omitted.
It'd cost me about $10k to replace the stack of Commodore equipment I gave away to a scrap dealer 20-ish years ago, if I bought it all used now. But I'm still tempted to start, maybe with just one or two pieces.
I recently picked up a used Epson HX-20 for a very reasonable price. It's still an amazing design, and could probably still be used for actually useful tasks.
I have the Olivetti M10 version of the HX20 - its very definitely something I could type on all day, writing a book or some such thing.
My iPad with smart keyboard, not so much. I just get distracted by all the apps.
