Yeah, general (worldwide) availability is an issue, as we've already alluded to:

It's indeed a bit of a trouble making a list that is valid worldwide. Some products / manufacturers tend to be based out of the EU and offer low prices there, and same for the US. If you want those products in the other continent, they will be much more expensive. Then ofc, one could make a list for direct imports from China (mostly only available in bulk) as well.. I mean, everything is produced there anyway.

Found them cheap on ebay as well. I also looked at MTX RT12-4 recently since it's cheaper than the Alpine. But on Amazon and ebay Alpine is cheaper.
