Can you expand on the benefits of the Pro model? The usefulness of the included air filter and pass through slots have been explained on your site, but the laser and cooling upgrade aren't really ever discussed. 5W more power doesn't seem like very much of an upgrade (12.5% more power for 60% more cost).
Sensors are easy to install in a converted K40 and the protection of the laser tuber certainly warrants the installation annoyance and cost of a flow sensor. It is also desirable to know the temperature of the water and the tube. This post also outlines the installation of an inexpensive water temp sensor and control.
