Personally I have shopped Daz rdna and renderosity and any problems on any of these site have been addressed in a very efficent,and/or apologetic manner.(knocks on wood) As for the Euro US dollar thing-- I think it would just be best for you then to buy it in US dollars, AND write to the company and tell them how displeased you are with this practice. You never know what could happen if you approach people in a polite way.
