1 - I like to consider myself an expert eBay-er (my ebay account can legally buy alcohol in the US, and I am myself only 36 years old) but I have not found any ZED-F9P for less than $90 ish. I am aware of the Quactel (sp) modules, and am considering a set for some RTK experiments. Is that what you're referring to?
2 - I've thought about replacing with ocxo but the pads are tiny. My soldering skills aren't nearly as good as my ebaying skills.
3 - it is outputting 16 Hz, chrony is doing dpoll -4 poll 4.
4 - I have done tempcomp (it is not active for the post referenced by this HN post). Fun stuff and probably my next writeup.
there are good deals on ebay atm. e.g. brand new ublox zed-f9p dev board pin compatible with the M8T receiver you are using. it also comes with dual frequency antenna. it is not a second hand chip, but a brand new module ready to be plugged into your system.

I usually buy my second hand electronics stuff from www.goofish.com, the home base of all those "From China" ebay vendors.
