Have you tried their website?
They use to have a listing of all the adapters AND the wiring of those
adapters, so you could make one yourself.

I don't think that is correct. I've had an S4 for years and don't remember
them making the plans for an adapter, to make it yourself, available.

Many of their adapters aren't just socket changers, many are multi-layered
and have some onboard logic.

I think the pricing is fair for them although some do get kind of expensive.
Just amazes me they keep supporting that thing (S4) being it's been out for
like 15 years now.
