The shop is reluctant to do it under warranty (they probably don't have the right gauge either) and after waiting so long I'm just about done with the brand. Time to start trying some new shops and brands I think.

I have heard of that yes, but not experienced it on my machine. You would be using your machines way more than I do with my BR600 backpack blower.
I'm assuming you have the KM 131R? Considering you already have the Kombi tools, I wouldn't be starting from scratch if the tools are still in working order. Stihl offer two other Kombi engines -
KM 56 RC-E - This is the domestic grade engine, 27.2cc with the traditional 2-Mix two stroke design. I actually have this unit myself, the engine on these are pretty well proven but would be a step down in power (0.8 kW vs 1.4 kW)

KM 94 RC-E - This is the mid grade unit with a 24.1cc 2-Mix engine. Power sits at 0.9 kW.

If it were me, I would just go with the domestic version, it's $170 cheaper and by the time the engines on it's last legs, the tool attachments would be at the end of their life also.
