I think BP already has two transceivers and needs one more.
Now I'm calculating the cost of getting 3 units and asking myself if I really, reeeally need them.

Skyports would be $300 + 180 + 180 = 680 ($180 for additional units according to a pro tog)
PWs would be 265 x 3 + shipping (dunno ... say $100 max) = 895 + 7%GST = 957.65, or nearly a grand.

I could do a lot of other things with a grand. The skyports are beginning to look a lot more attractive right now.
