I’m glad you asked! I’ve been wondering the same thing for quite a while, but thought they cost thousands. I had to go look up prices right away, and came across this article for beginners basic printers, 4 different ones, with lots of info.
I am going to start looking into it more, but thought you might like to see this article too. It is from 2022, so prices have probably gone up, but still all are under the price point you mentioned for the printer, and the inks seem reasonable, compared to inkjet, which always seemed to dry up or run away!

I’ll check back to see what you find out! I’ve got some fantastic photos of grandkids that I would love to get busy practicing on!
