My favourite resin from Digital Forge is no longer available thanks to the pandemic.  
So far I have eliminated the following alternatives:  
Formlabs V4 - too expensive and doesn’t meet specs for thin walls and minimum overhang.  
ALW - Tried some, went bad after about 3 weeks. still have over 1/3 litre unused.

I’m looking at Photocentric and some of the Moai resins. Anyone have any experience with those or any others I should check out?

ALW going bad - how did you assess that?

It worked ok for about 2 weeks, although I was not happy with the glossy appearance and the smoothing out of fine details.  
See this thread for details:
