Ask yourself why Emerald doesn't advertise, no need to, althoug he(Dave w) writes for PPC he is not even listed in the rolling road listing.
Has recently been looking at another RR as an addition, not a replacement, so they can get through the backlog a bit quicker.
I can honestly say I have never seen ANY emerald of any age or version that was supposed to have something/feature that didn't work, and or was not sorted foc by emerald.
I have personally been there whilst another person's mistake on putting cars together have resulted in fried ecu(lambda wire dropped on exhaust, in trans tunnel, as plastic clip melted), this was a car from I think either Sweden or Switzerland, and was catching the following mornings ferry back(on trailer) dave and karl did a repair on ecu FOC repaired loom FOC, sorted car ready to go, no extra cost whatsoever, I know this is the case as I was there, and had to put my playing with a few settings off as a result of it.
I use K3 myself, I have known plenty of times basic silly faults had to be fixed on cars first before engine even ran, and there has been no extra charge.
They are the most down to earth people there is, if he doesn't think it would suit someones needs he tells them, back up is very impressive.
What you have been offered(above) is a great deal, rip his arm off imo.
