I think Bill Wann is making a 150w UV now and for the size the price I didn't think was bad. Let me hunt for it.
Edit, I didn't see it on aquarium engineering site, but check his facebook. I am thinking they are 1k with extra bulb.
Here is from his post:
Our new 150 watt Uv sterilizers are ready to ship . these are made out of the thick wall uv resistant pvc tubing with your choice of inlet and outlet fitting sizes , from 1/2 to 2 inch . all units come with a GE quartz sleeve with is superior to the other units for sale in durability and clarity .
Bulbs can be changed without turning off the water flow and we only use high quality 150 watt Amalgam uv lamps with an extra long lifespan .
Each unit is shipped with two bulbs so ...that you have an extra and no excuse not to change the bulb .we will also be selling the bulbs at a discounted price to our customers only for 25.00 per bulb not 100.00 like everyone else does .
The price is 999.00 with free shipping in the US .
