Forget using your BUD. SC uses 30 transponders on F1 and 17 on F2. You will have a burned out polarotor in no time. In addition, the wait as the dish moves back and forth between F1/F2 will become very tiring.
Go with electronic swtching between satellites and polarity.
Use either:
SC 75 cm elliptical dish (has built in 4 port multiswitch)
or
find 2 old Primestar dishes (that are the same) and use a DirecTV multiswitch to tie them together.
As for pricing, don't forget taxes (7% GST + provincial tax which is 7% in Ontario). Result is that price in Canadian$ is about the same in US$ when taxes are included
