For the purpose of temporarily compliment I know someone who might lend me a Super Isolette, and of course, in the auction sites one sooner than later starts to look into the Super Ikontas and exotic machines together with knowing the usual caveats of vintage cameras. I do feel I should have gotten a Perkeo with Color skopar earlier for such purpose.
-> For an expedition indeed the interest is to have the best possible quality, but for fun I would say the Nettars and equivalents are fantastic. Holgas aren't that well performing nor cheap anymore!
Prices for the Super Isolette are, unfortunately, so inflated (500€ minimum), they are probably not worth it anymore. And while I haven't owned the Super Ikonta 532/533, at well over 1 kg I can't help but feel that I might as well carry a TLR.
That being said, if you can find a local German seller (kleinanzeigen.de) willing to ship outside of Germany, that's probably your best bet for a Super Ikonta III with a Tessar at a reasonable price, i.e. under 200€.
