Oh I don't know about the Kenko being a better value... for the price, and selecting my bids based on the attached lens, I bought two SP1000's with Takumar lenses for an average price of $43 delivered. Both work fine, with no problems. The one I kept I did have to soak the bottom plate to loosen the battery cover.
Even spending $75 every 5 years to have a CLA and whatever fix, the camera costs me less than a new Kenko would. Granted, this is a screw mount setup. (However, I think I paid even less for my mint Program Plus with smc-a 28mm lens)
Further, spare parts are likely to remain plentiful for Pentax as broken cameras get cannibalized. I wonder just how available spares are for the Chinon from 10 years ago?
That said, if B&H had one for sale I'd be over there, fondling and figuring out how to smuggle one home
