I'd love a Nikon S2 I don't think I'll have the budget for it soon, thus my request for fixed lens rangefinders.
Brian, I knew about the Konica III (M?) and it's definitely on my shopping list, but they're not so common and tend to fetch relatively high prices. The Signet 80 looks interesting though.
There's also the Agfa Optima 1535 which might have a 1:1 viewfinder (and I love Agfas), but they are pretty rare too.
