The cool thing about the Trimbles, and similar, is the grat hold-up
time for PPS.  Some specify an accurate PPS for a day after signal
loss.  A modern PPS, like a Venus 828F will perform as well as a
Trimble as long as it has a good lock.  And good lock is easy with
the super sensitivity these have.

ddrown just put a Venus 828F in a metal bag, and it STILL give him good
PPS.

I coulda told you that.

Well, we would need some more parameters: quantity, electrical needs,
interface type, weather sealed, mounting needs, etc.

I find the BU-353 to perform pretty well, if you can buy the -S3 version,
not the -S4 version.  It is in a weather sealed case, magnetic mount.
