I also have an Anycubic Photon S with the dual z-axis rails, and it is a great value for printing small scale models. There is a steep learning curve when it comes to the orientation of the model on the build plate and the placement of supports, but the level of detail you can achieve with resin printing is worth it.
With intelligence, anyone can operate a 3D printer,
With knowledge, one can determine the best subjects for 3D printing,
But with wisdom, you can convince a friend to purchase a 3D printer and operate it on your behalf
