Do you mean RMM at Mountain Electronics? He also has modified units with much improved User Interface and greatly increased output for $10.50 more than the basic $40 unit. He does charge shipping but lights ship from the USA and I receive my orders within 2 days of their being shipped. Customized lights take about 2 weeks currently + shipping time.
He does ship to Europe but you have to email him as the web site checkout software cannot handle international orders. Not sure if the star firmware change only can handle it but I have a stock M6 and RMMs level one modified one and the Turbo level output is most definitely higher than the stock light. You might also note that the RMM lights have XM-L2 LEDs as stock compared to XM-L emitters in the farfarled listed light. That is also what came in the one I ordered from farfarled about a month ago while the XM-L2 LEDs were in both the Level 1 and level 2 modified lights I have bought from RMM.
