It was nerve racking.
And honourable mentions and loads of thanks to Parker (thanks Paul, Andre and David), Coastline (thanks Brian), Barnett (thanks Laurence).
All of the above were serious contenders, and gave me lots of time and support. I would have been very pleased to have bought from any of them.
For reference I also considered Tohatsu, JBT Marine (Ballistic), Ribcraft, Osprey, Ribeye / Ribtec, Ribsmarine, Rib-X. These were all possible solutions, but for various reasons did not meet our needs.
But above all can I thanks those of you who put up with my indecision and answered the many, many questions... some of which are still being asked.
If I can pass any of my (dubious) wisdom and experience gleaned from the buying process, please do not heistate to PM me.
Now I have to wait until mid September.....
