Not really.

$500 SLAs gives you LCD SLA printing with medium resolution.

You will need at least $1300 for a Moai kit(with Laser Galvoes):

Or at least a $1500 DLP kit with a good resolution for creating small parts.

Fo really small parts you need the strength of steel or titanium. But you can made then in plastic, metalize the plastic and use something like EDM(electrodischarge) to make your parts.

What do you mean 'medium' resolution? The Moai has 70 micron laser spot size. Form2 is 140 micron. The $500 SLAs have 47 micron pixels. They have major disadvantages vs the expensive laser SLA machines but resolution is not one of them.
