I'd save my money and get a gun with a known performance history.
I know "get a Glock" is a meme these days, but you could do a lot worse. Same goes for a used S&W revolver. S&W M&P pistols are going for cheap these days as well and they're considered to be part of that "Gun, Qty 1" ideal. Even a used Ruger plastic 9 is not a bad choice given Ruger's support. I've seen LC9s for right at $200 in the used case.
Or, buy the cheap gun because it's...cheap. We'll get the popcorn ready for when you can't find holsters, spare parts, or for when proves to be the POS it appears to be.
