Valve spring drought

Valve spring drought
Ok so recently, as many people building Miata engines have found out, just about all of the cheap Volvo sealed power VS855 springs are gone. At least I can't find them at a reasonable price anywhere.
There was a new post on the old BP valve springs megathread about another option with the part number: "418737" these are more Volvo springs of apparently the same dimensions and seat pressure as the other Volvo springs. However, the only reasonable price I've seen are from a German site where they are going for 6 and some change Euro per spring. Not bad until you include 17% vat and shipping to the Americas. Roughly $200 to my door for a set.
So that leaves me asking: What should we do? Can we just buy supertech single springs and use the stock seats?
I'm really not aiming for the sky here, I just want to refresh the springs in the 150k mile VVT head that's going on my forged bottom end, and it seems like a shame to spend the money on all forged everything and not be able to safely rev to 7,500 or so.

It was pretty annoying when i was looking a few months ago.
Ended up finding some on summit or jegs that price matched Rock auto.
I think it's going to be interesting finding a backup for when they're gone. I'm with others that wanted more spring without shelling out the extra few hundred for the ST dubs.
