I just got half a dozen from Spencer Jack in Winnipeg - shipping was $60, I think, for 6 healthy, 6" fish. Great service, selection, and the price was fantastic!
Canadian Aquatics is very good also when I had my Bichir tank going they are who I impoprted them through. very high quality and large sizes for a good price.
Bichir (Polypterus sp. Lapradei) 10"-12" 4 $60.00
Bichir (Polypterus sp. Senegalus) 6"-9" 14 $30.00
