Hey Footie,
I used to get my Micargis from a friend who owns a bicycle shop. Then later I opened an account with Micargi bicycles.
You could try a local bike shop, if they dont have any Micargi's they might be willing to order one for you.
Micargi Bicycles INC
I know BikeBarrymotors.com used to supply Micargi's don't know if they still do.
I hope this was some help....
