What I'd also add to the above ^^^ is specific to the StingRay Special; for me its head and shoulders above any other 'Ray variant I have played, be it USA Classic, old series, Sterling or even the old SUBs and OLP licensed models. I can't even pin what it is, but it just has a premium "feel" to it that I don't recognise from before.
The higher end Sterling models seem to be great instruments for those who don't want to spend US prices, but as with the majority of brands, it just isn't quite the real thing. I would always go for a used USA 'Ray over a new Sterling for the same money.
