Well,

After 7 years since last posting on this thread, I still have the PPI-15.
Still going strong, and still hardly any info about these guitars, they really must be a rarity, so I think I'll still be hanging on to this instrument forever probably!

Yes I agree with others, for fingerstyle it's great, especially because of the generous neck width, but for strumming, not the big open sound that some other guitars might have, although as always, sounds are subjective. Anyway, I still love this guitar.
