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