Question for PSP collectors in India

I’m curious about the current availability of the PSP-3000 in India. Since it was discontinued quite a while ago, I’m wondering whether sealed/new-old-stock units are still known to exist here.

For people who collect PSPs in India, how common is it to come across original PSP-3000 units that are still factory sealed? Are there any particular things I should know about identifying an original factory seal versus a resealed or refurbished unit?

I’d also be interested to hear about the history of PSP availability in India and whether there were any official/local channels through which the PSP-3000 was originally distributed.

Not looking to buy or sell anything through this post just trying to understand the Indian PSP market and how collectors verify these units.
