I've been passively looking for one recently as well. There was a post about a month ago which basically stated that Angus' is the best one to source at present BUT that there really is not availability for a GREAT 127 in the market right now.
The one from Angus apparetly has a good dial, can be had with real saphire, but according to most here the engraving on the movement and movement quality in general is not good on the current offering. Also it apears as though while he offers superlume and a canon pin fix most have stated the lume is still not great and rather than installing a tall canon pin the watch instead had hands that were filed down.
Due to those details I've decided to continue to wait for a good one to come along either second hand from a member here or until the dealers get a better version.
