I have a Star BM. It is remarkably accurate. Even shot it at 2 gun once or twice.When I first got an auto loader 9mm I had zero cash that was not for thrown at the ladies or bartender.
Star had the 9mm BM. Heavy for it size. Not a lot of rounds but it worked and was pretty accurate. Traded it off at some time and wish I still had it. New surplus price to me was under 100 dollars. It spent a lot of time in a truck glove box and in the garage tool box top right drawer. Nobody seemed to laugh at it because of the 1911 look.
Llama made some interesting items in the cheap range. Bersa with the PPK copies which fit the hands very well. While shooting others bersa’s and llamas they seem to have either over harden firing pins or extractors as I replaced several for buddies who had them.
The Jennings 22 listed had so many companies made them some are great and some not so much. I think somewhere in the parts box is a version with no spring or rod.
If I was looking for a inexpensive backup/carry/glovebox/tool box drawer style gun the star would be one I would look at.
