Only one from my side: ALPS! Aaaand: ALPS! That´s my opinion after some years of DIY (I did NOT try P&G up to now - as I´m totally addicted to ALPS in the meantime). The best price-feeling option you can get in my opinion.
Certainly, ALPS offers the whole pallette of switches/pots/encs whatever. The only question is, where to get it, as there are not to many distributors. Just search, google, ebay and so on.

Cheers mate - have been speaking with Alps Distributor and have a special order from Japan being spec’ed now, so fingers crossed I’ll have my uber pots soon…
