I used David's Get Started list for the mill and only those shown in "green" as Must Haves to see how deep the rabbit hole was to get started. I used his links for the prices. I only included those things for a mill, none for a lathe only. 29+- items, cost without shipping or taxes came to $2940, my local sales tax is 7.5% which adds $220, Freight ?? at least 10% $290 for a grand total of $3450.
I'm cheap so some of the quality items on his list would be things I'd go for a cheaper substitute to get started. That said, I've upgraded some of the cheap stuff I bought when getting started. I didn't include any cutting tools, sharpening stuff, roll around tool cabinets, bench & vice, or accessory equipment that is necessary (bench grinder, metal cutting saw, etc.) Add those if you don't already have them. There are lots of small items you will find desirable but are "as needed" things.
If we can help you spend some more, let us know, we seem to be good at it.
