The 7i90 in SPI mode works well with the Raspberry Pi 4, and probably
the Pi 3 too. (There's an issue with SPI on Pi on Debian Bookworm, but
it works fine on Raspberry Pi OS Buster.)

6 available, for $60.
You have to flash one of the SPI firmwares on it, using mesaflash.

Two problems.
One: $249US and two: out of stock at the moment.
Mind you, so is the 7i92H but it was around $89 and with two Chinese BoBs at $5
each comes in much cheaper.
So then the question is both require waiting. A Pi4 isn't cheap either nor in
stock.
And an ACORN CNC kit is $329. Looks like in stock.

It's hard to convince someone to go the CNC route with LinuxCNC when all they
want is simple 3 or 4 axis with none of the other amazing features that
LinuxCNC offers.

Ah. I forgot about that little tidbit.
SPI (Such as 7C80) ought to work though.
