[ginormous thread bump]
Just learnt a neat trick - it's actually possible to manually control the pressure, by carefully controlling the release of hot water, during the brew. I don't know yet whether this will improve my shots, but this simple technique will allow me to experiment, and has stopped me considering the idea of upgrading to a better machine, or fitting an OPV to this machine. (for the time being)

Fluid-O-Tech pump in EM6910 to lower flow rate/reduce pressure?

A coupla thou or so ought to be sufficient to purchase the the gear pump and motor from the Ambient Vesuvius as well as the 2 boards to operate it and the pressure control interface. Might be overkill on a sunbeam though

Fluid-O-Tech pump in EM6910 to lower flow rate/reduce pressure?
I know I'm over-obsessing about brew pressure, but just while it's on my mind, I'm curious to know how well a Fluid-O-Tech 1106 pump would go in the EM6910. The reason for asking is that I found this thread: The importance of brew pressure, purpose of adjusting OPV? - Espresso Machines • Home-Barista.com which mentions that this pump's pressure vs flow rate curve appears to be better suited to espresso, if an OPV is not present.
Would it be a drop-in replacement for the EP5?
Would there be any problems with the back flushing with this pump?
I've received advice here recently not to worry too much about brew pressure, and I am not ignoring this advice. I am just interested in the topic and am doing research whilst it's on my mind. (even that aforementioned thread mentions that temperature is more important)
Thanks again,
