Yes a DLP projector itself does contain more parts than a complete FDM printer, but to a DLP printer a DLP projector is just one component that can be replaced easily. It is a component that is proven to be stable and usable for many hours at a time without needing replacement.

Resin isn't as expensive as it used to be. You can get it at $65 per litre. Your failure rate with DLP is much lower than with FDM so your mileage will be alot better with 1L of resin than it is with 1kg of filament. I have kilograms of failed ABS prints in bags sitting in the garage.
Complex nozzles may not be the way to go, DLP tech too slow
