I totally agree, Buy from Skyjack. In fact, Sky jack is usually cheaper than aftermarket. And, quality. Same with Genie, they are always cheapest source of parts, consistently. They offer all manuals online, free. They give support. Why mess around with cheaply made aftermarket parts that will fail soon after. The cheap switches and controls actually cost way way more when they fail. Labor and lost time to re-fix bad quality parts.
