Well MACNA is getting very close. We have our latest version (same as before, just different rear box height and color scheme) that will be on display and running. Here are some photos of it. Looking forward to meeting everyone and explaining what makes ours different and why they cost a little more. One reason is R&D, we spent years testing this design and it is built for longevity. The ebay one especially is notorious for warping after a few months. We have had a lot of customers switching to ours after finding out the hard way. We do not skimp on materials or assembly. I am a avid reefer like you guys and like to save a buck or 100 bucks when I can as well, but in the end this is the main piece of equipment that links your life support system under your tank to the tank. So if you have one fail then the money saved may be lost elsewhere. Just my thoughts. Being in the hobby for over 25 years I could tell you stories all day long about cheap equipment failures that I have had.
