FWIW, I am fairly certain that if the PID goes out in a Tsunami, it can be swapped out with relative ease (mine has become a bit loose up against the body, even); same goes for the coil. The big machined billet piece is just a platform, airpath, mounting point for the coil and draw tube + bucket, and enail housing altogether, after all. I feel you on fretting over/anticipating newer models, though. I have the standard-version Tsu, acquired shortly before the MaxVapor collaboration was announced, and am heavily considering the MV version. So much for VAS being sated...
Thanks
