Spare fresh water pump

ngtnewington Newington

I have been following the various threads regarding replacing the freshwater pump.
On Amelia the pump with pressure vessel works fine but I have no spare and it sounds like it is only a question of time.
In the screen shot below are two pumps from Marco that look good. My questions are-
Is the electronic 14E really worth the extra cost?
The 12A could be used with the existing pressure vessel, whilst the 14E could be used without, right?

How reliable is the electronic controller for the 14E?
