Been testing the Ember Printer the last few weeks and so far I really like it. Cannot speak to the longevity of the Vats but I think you can buy two for $100US whenever they get cloudy. Their printer design and resin are open source and it allows you to use any resin you want. The accompanying software is still in beta right now, so you have to upload it to Autodesk's website to convert to the file type the Ember needs. They recommend Meshmixer for adding supports. Not as fast as other resin printers I've used, but the quality is very high.
