i use a very cheap uBlox NEO-6M gps module. the 1pps pulse has been shortened to 1ms, and i haven't disabled SBAS (which should further help with jitter, but i forgot to do it).
I have a uBlox UP501 it's not good but not as bad as some for jitter.

it works very well with vlfrx-tools (haven't looked at the code, but
probably Paul included some magic code to average out jitter).
Speclabs magic interpolates the 1PPS pulse but I can still see jitter
from the modules that have it, I was wondering if would cause problems.
I had to work on my Trimble in order to use it but it is solid.
