Mode S is more desirable as large portion of the airspace will be only
available for gilders with engine if the glider is mode S equipped after
31 March 2008.

If connected to a certified GPS your mode S transponder can emit the
current position and altitude in the extended quitter, so that you are
visible with much higher accuracy on TCAS of the big boys.

Thanks everyone. Can you tell me why mode S is more desirable? Even
with mode S, I don't think that I could display traffic on my PDA.

Any opinions? I plan to install a new Becker transponder in my ASW-28.
Should I go with the old mode C unit or pay extra for the new mode S
unit? Thanks.
The new Becker mode S unit is about the same price as the old A/C.
Its 2,064 Euros (plus $200 for an ACK-30 encode).
This is what I got for my Antares 20E... See:

Several stores offer the mode C Becker for less than $2000 US dollars,
so you might want to check around if price is important; otherwise, it
is more desirable.
