It's again time for hunting down old postcards of Hungarian settlements of your interest - Profila Ltd. of Budapest, Hungary offers 4000+ of those old postcard at their auction on 15 Dec 2003. These cards are not cheap, tough: the less attractive ones start at about 1400 Hungarian Forints (7 US$), average is probably about 13-14 USD.

Starting prices for postcards with synagogues go the sky: cheaper ones start at 35 USD, and I see a corny one of Kápolnásnyék for 80,000 HUF (~360 USD). It just doesn't make sense for me.
