Yeah I agree with awerby, there's no way to compare what exist to what doesn't. But I am very happy with my Form 1. The Solidator is the kickstarter printer which I have the most interest in right now, but I couldn't afford anything now either way anyway.
@jimc, no-one I know of has had any success with Madesolid resin in their Form 1 yet, I have experimented with B9 Cherry mixed with Formlabs but with very limited success. But with the rate at which all these things are coming to market I'm sure there will be even more options soon.
