If you want an evaluation board for a different chip, surely you would buy 
a different board?

For NTP, Chris, what aspect of performance is inadequate?

No special cable needed, just one or two extra links on the board.  I see 
it as a very low-cost solution which is adequate for the job in hand.  The 
sub-microsecond level performance of higher-cost solutions isn't required 
for NTP.

Anyone wanting a no soldering solution could get the ready adapted GPS 18x 
LVC, at a somewhat higher price.
