OOPS, forgot about the harmonies! I haven't bought the 60" off brand but have considered it.
I have purchased sets from a seller in Indiana in 16", 24", 32" and 40" all for under $40. And I got a set of the DPNs. It's a fantastic deal if you have a budget or change sizes alot. The only down side I've seen is that the cords are thicker than the Brand names.
