Are these units generally available yet? If so, where can I purchase one? If not, any idea when they will be?
Thanks.

No U.S. retailer has stepped up yet. You can buy them qty100 from NaviSys.

They don't work that we'll on FreeBSD.
I've not yet tried Linux.

In a word: jitter
The PPS API described in RFC2783 isn't supported on USB serial ports on FreeBSD 8.3 or 9.0
Note that the PPS API *is* supported:
http://fxr.watson.org/fxr/source/sys/timepps.h?v=FREEBSD9
http://fxr.watson.org/fxr/source/kern/kern_ntptime.c?v=FREEBSD9
But that timepps.h is only included via uart/uart_bus
http://fxr.watson.org/fxr/source/dev/uart/uart_bus.h?v=FREEBSD9
Compare:
http://fxr.watson.org/fxr/source/dev/uart/uart_core.c?v=FREEBSD9
and
http://fxr.watson.org/fxr/source/dev/sio/sio.c?v=FREEBSD9
and
http://fxr.watson.org/fxr/source/pc98/cbus/sio.c?v=FREEBSD9
to anything found in
http://fxr.watson.org/fxr/source/dev/usb/serial/?v=FREEBSD9

And how much jitter? The lack of RFC2783 should not be noticeable since
the jitter on the USB serial is so large. RFC2783 helps in the
micro Second range and the USB serial is in the milli Second range.
So with, and without you are going to get about 1 milli Second jitter.
So, what problem are you pointing up with *BSD?

ntpd won't enable the PPS stuff, because the ioctl to 'discover' same fails.

I have no desire to own 100 of these. :D What is the next best USB based device?

We know of no other USB GPS providing PPS.
If enough people wanted a GR-601W I would do the bulk order and reship.
So far I have only heard of a few people ready to buy.

Yea, well as one of my plans was if gary didn't step up, would be to
try a pre-order campaign
on amazon (via my company, teklibre) to get to the 100 unit goal.
Actually, to get a custom silkscreen will take 700...
Alternatively use 'em as kickstarter/indigogo swag.
or make it part of the worldwide testbed rollout.
Or all three.

FWIW I would be willing to buy one initially and after testing possibly a few (6 or so) more.
