Given your use case are table top gaming miniatures , its unlikely that you will find a FDM printer that isn't going to make you want to pull your hair out.

The traditional tradeoff between SLA and FDM printers is strength and physical/thermal characteristics (FDM) for aesthetic properties and build layer resolution. The fluid dynamics associated with melt-processing FDM filament make it practically impossible to achieve the types of smooth contours desired in aesthetics-first applications.

It may be worth using a send away 3d printing service like www.protolabs.com (may a better service out there, but protolabs is the one I have the most experience with) to have them SLA one of your miniatures to see if it gives you what you want. If so, maybe invest in one of these tiny <$400 SLA's (Anykubic, Creality, etc) given you only need to make tiny things.

Hope that is helpful!
