my question regarding postage was intended to help you to assess the potential number of parts that could be sold in EU (excl UK).sold ten pieces for 150 each
It seems including shipping you will have to ask for 200AUD ~125€
Guess you are making this assessment far too early.Judging by the lack of response there seems little interest,
As example I'd make a decision only after a trusted source in the community would have tested it for 6 months or so.
Hope that helps.
