hi pentaxuser,
thanks for the good tips. I have been looking on ebay lately and even though there are seller that can ship, the shipping costs are (of course) too high. I will definitely try to contact both Secondhsnd DArkroom and Nova as suggested!
Regarding the closed darkroom, it was part of an art centre and, with no apparentr reasons, they decided to do not sell the stuff!!!
Thanks a lot

Mirko
