Well for $87 I have a linear Actuator, for $49 I hope to have a LED3xS24VC3RI for a little more than $50 I have the steel, and I also am like Xringer, love fiddling. Also mine array is grid feed, and an increase of maybe 30% on 9x175w panels is cheaper than a new panel, and you can't get them for $186 plus fun and labour. I have cows on my farm, but it would probably be cheaper to go buy a bottle of milk from the shop, but thats why I live on a farm and not the city. Easy to buy a tracker for $2000 but have you ever tried milking a cow
