I keep trying to find some of the 10ft 30pin>USB cables that will work reliably with my iPAD, as well as 10ft Lightning>USB for my iPad Mini. Has anybody found any? I see a lot of cheap ones on ebay, but the reviews on most of them are not very good. As much as I hate to say it, I would even pay Apple prices if I could find some, but it looks like they are not available even via the Apple store. Thx.
