Theres better but there really isn’t cheaper. An Xbox Series S is $300. That’s a controller and a very relatively good APU even if it’s artificially limited.

I have a MiSTer FPGA and it definitely cost more than $300 and it cannot emulate anything newer that PS1 or Sega Saturn.

I totally agree but it just reminded me of a discussion I had with someone here a couple weeks ago where they talked about the "great advancements" Microsoft has made in the console space compared to Sony and this was one of their primary arguments.
