As an example of printing quality for prop weapons, I modeled and printed the Alliance Pistol from the movie Serenity.
I can only speak for the printers I have experience using and for keeping the initial cost and clean up time to a minimum.

It's not a perfect print, but for an inexpensive option (in my opinion), the CR10S and ENDER 3 models are a good choice. It can't of course compete against the more expensive choices.
A little sanding and a good paint job, this example will turn out to be a nice cosplay prop.

Another example of many, many prints....

Good luck on your choices and Happy printing

On a side note, be aware however that the Creality CR10S and the ENDER-3 are both open frame printers (not enclosed) and
will require some assembly, proper set up and tuning.
I bought my E3 as a kit and it did need to be assembled (but I knew that going in).
With proper understanding that it is only a machine and doesn't have the slightest idea what it is printing,
it is up to the user to make the best adjustments and measurements to help the printer do the best it can.

Both will require a fair amount of "user interface" and intervention and are not "plug and play" machines and they will print PLA fairly well.
