A thermostat is easy to replace on the euro 3.
It does, yeah. It seems that access to the bottom bolt of the thermostat housing is a bit tight and involves moving the power steering components, aux belt, etc. out of the way, something I don't have a problem with; it's the putting things back together that gets me nervous!

It seems there is a resistance measurement that can be made; should be around 3 ohms.

My local Volvo dealership wanted £104 for it and were happy to have it ready for me sometime in May. I followed a link you posted on another thread and was just about to purchase it. I'm happy to take you up on your offer. PM incoming!
On another note, what do you guys think about using a primer bulb on the inlet line to the HP pump to prime it, as opposed to pulling vacuum on the return line. Something like this, perhaps with some clear tubing:
