That spec is certainly exotic, especially if you want bowthrusters too, but far too large to fit in my boat - and £79.
Just to correct any misunderstandings, P94 is NOT designed to run a bow thruster in addition to the two main motors. As the instructions state, the connection (at pins H2) for a third speed controller is straight-through from the throttle stick and is intended for a central motor or a P100 Noisy Thing. The bow-thruster in a conventional twin-motor model is controlled from a third channel via a separate speed controller. You can't run throttle, steering
and a bow thruster properly from just two connections to the receiver. P94
can be used (in Mode 2) to operate a pair of stern- and bow-thrusters but you would need another unit for the main motors.
As regards the price, two 20A speed controllers and a W-Tail mixer from another well-known manufacturer will cost £73 at current list prices. The footprint of these three units together is very little less than one P94. You then have to connect
and set-up three separate electronic units and you'll finish up with two high-frequency ESCs (which have been known to make some motors squeal) and a mixer with none of P94's different operational modes and adjustments. You've saved yourself six quid.
As someone used to say, suit yourself. BTW P40C is £28 to UK+EU customers.

Forgot to mention that P94 will shortly be available with Autoset, which means no fiddling about with transmitter trim levers to get the motors to stop and start together - and, of course, no flashing LEDs and buttons to push.................
