We have used the first one with good results two and three are probably the same and on closer look I would stay away from them. The ublox is not even a timing receiver I have done stuff like that on a 2 by 2 inch board calling it a GPS PLL. Number four  most likely like 2 and 3. Get the first one, also best price.

 I'm looking for two more receivers to implement "Pair and a spare" redundancy for our engineering lab and production.

Are these below compatible with Lady Heather?
Any thoughts as to overall quality etc?
Any other suggestions?
