Hi, They are the _only_ guys in Hungary I know of who sell onewire stuff:
http://www.hteurep.hu/alkatreszek.html No webshop, no pricing or stock availability info. You need to call :) I used them and a Polish webshop I can't recall right now. Availability of parts is a real pain in Hungary. They both charge 4-5 times the US going price for every onewire device. I bought an USB dongle at the time, which works well - I had no issues with it for over 3 years but I guess that has already been discontinued. You need to call them to find out what they have.
