Sailplane equipment: transponder, transciver 8.33 kHz.

Hi.
I'm searching for the cheapest SSR transponder and transciver with
8.33 channel separation that could be mounted on a sailplane. I
actually don't know if this must be brand new, its just have to work
properly in Europe.

I've found some products of MicroAir but the price for new stuff is
quite big... Around 10 000$ for both.

Could group-mates tell me how much this equipment must cost, and meaby
some examples/models of stuff?

Sorry for my broken english. I hope You've got the point of this
message.
