Before diving in, do yourself a favor and make a want/need list of the basics first. Then remember that with machines you also need measuring tools and other "support" equipment. As suggested already, with machinery you can make quite a few items that will only improve your capabilities. Quite often fabbing your own tools/tooling is as rewarding as finishing those other projects you bought the machines to support.
As always, I suggest people visit a library or two, as well as the used book stores that still exist. Quite often your local library wont have very much of a metalworking selection, but many have a free "interlibrary loan system" where you can pull books from potentially millions of libraries worldwide, and I think you would be surprised the extent of books available free bc of this. I was never much of a "reader for pleasure" until I began reading books related to the trades. Strange how this hobby has turned this young man's life around.
