Find an older Dish Network "Superdish" for free somewhere. There's a c120 flange lnb installed in that cluster of lnbs. It's bandstacked, but works well. It's also fairly small sized. It's labeled so you can easily tell which one it is. Otherwise you can buy a c120 flange Invacom lnb off of Ebay, but they are pricey, and you might have to wait for it to arrive from Europe.
