RE: Quick 60 questions.
I had a Quick 60 for a while and I liked it for the most part. It has a pretty good design, reasonably smooth, and was plenty powerful with the OS.61WC. I never had any big problems dealing with HHI. Most of the folks were helpful and friendly (even the "boss").
The things I didn't like were the belt driven tail (personal preference mostly), no provision for a constant drive tail (that may have changed now?), and I didn't think the quality of the machining in some parts was exceptional.
Would I buy another one, probably not. Would I tell someone else not to, no.
