Hi all! Probably mostly to Canadian WindyNation supporters. I'm on the very cusp of buying a Windtura 750. I bought the blades a month ago, hoping that I could use them on my Whisper 1000, and I probably can. But in the process of putting it all back together I noticed too many other worn parts, exposed wiring being one of them (poor design. I can see small green dots on some of it). Anyways, what I'm asking about is the duty being charged. I understand that there's duty charged on alternative energy product parts, but none on whole units. Has anyone experienced this to be true?
