do you want a full unit with frame and heasink? as mentioned it will cost a lot to ship.
however, I have 6 units that are stripped down (and pencil modded to enable operation without heatsinks) - thats 12 hashing boards, 6 controllers, and the applicable wiring. without the bulky frame and heatsinks these would be much cheaper to ship. Currently they are all fastened together as seen, and im appy to sip it that way (should be <$30 in canada and <$45 to USA)
