Which printer is the best to build?

Which printer is the best to build? I already have build 2 delta printers and have an Ultiamker 2, but I would like to build another printer. Would the Herculien or Eustathios be better for the implementation of an 80c heated camber? I was thinking of printing all of the plastic parts in polycarbonate to deal with the heat from the camber.

HercuLien would be best for that. It is designed to be enclosed.
