I have been using Form 2 for almost 5 years now. Very reliable 3d printer but their resin is expensive.
You can only buy refurbished one now https://formlabs.com/store/form-2/ .
Resin printer are very cheap now. I have not used any other SLA 3D printers but you can find 1 L resin for $20 ~ $40 on ebay https://www.ebay.com/itm/US-ANYCUBIC-UV-405nm-Rigid-Resin-500ML-1L-for-LCD-3D-Printer-Printing/392778019458?hash=item5b7364f282:m:mmEmM394o55VO4e6cvzA0iw.
If you are sensitive for resin odor, I recommend form 2 resin https://formlabs.com/materials/
I have a brand new resin tank but I can't print anything right now because rubbing alcohol is sold out everywhere from where I live.
