Bob, Jim - Thanks for the detailed replies. You have both managed to confirm the difficulties and unknowns involved in being a fledgling TimeNut.
I think that is what prompted me to try to avoid as many unknowns as possible by buying one that was at least guaranteed to work, especially in the un-locked mode because I'm not sure what my GPS viewing here will be like until I have a unit to play with. A problem we have over here is that there isn't the huge eBay market for such things, so choice is really limited to Chinese recycled/cloned stuff of unknown provenance. OK, I could buy from a US supplier but, and I will probably be jumped on for saying this, US suppliers seem incapable of finding reasonably priced delivery methods. A recent example was a nice slide rule I was interested in for $36, but carriage was $86 ... I didn't buy. Getting back to GPSDOs - given that, when locked, they are probably all quoted as 'close to Caesium' (British), I will still buy a new one, but more reasonably priced and then try to acquire an SC-cut crystal to start making an OCXO to eventually form the heart of a GPSDO. I like the comments about holdover and recovery from holdover ... one of you keeps talking about rabbit holes, I think I see one looming.
