[sdiy] Looking for 61 keys 'waterfall type' keyboard for DIY..

[Jean-Pierre Desrochers]

Does anybody have a clue where I could buy
one (maybe two) keyboards manuals 'Waterfall type'
(the ones with no lips on the key edge and with ivory color) 
like Hammond organs used?
I thought of using Hammond parts but
their manuals are heavy metal stuff !
Roland VK-8 series keyboards use waterfall type keyboards.
I know FATAR in Italy manufactures some of these types
but I'd prefer a North-american source, new or used.
Doepfer has a Canadian source for manuals but
they would order from FATAR anyway and cost $$$$.
So far I'm looking around for used stuff.. 

Any Hints ?
