By the way, here you go my experience :
Doomswell : Really quick in answering. Feel confident do deal with them, until they quote me the shipping for the same price than the board
, when others companies quoted me a shipping cost around 200$ (I'm overseas in Europe)
Walker Project : Got one answer, but no news still around 2-3 weeks.
Soulcraft : really good contact with Jeff, he answers quite fast, and he is shaping me a custom board, with color, design etc according to my wishes. Shipping cost was good as well.
