Yeah Tyresö is like 20km from where i live :D (I live on Södermalm). I was thinking about it, but it's been a hectic time at work for me so I decided to just take the easy way and do it all by mail. Recieved the kit in 1,5days and when I mailed them back Phil recieved them 4 days later (I mailed them on a Saturday so 2 days really don't count). I did not ask Phil about any possibility of going there in person the get the kit/make molds on the spot.
I had a feeling you might say something similar as soon as I clicked submit ^_^
I'm even closer, so I might be tempted by the possibility, it would eventually speed up the process.
But I'm still waiting on some of the impressions on twins/duals or triples before pulling the trigger. However, it's very tempting to take the first step into CIEM territory, as I'm sure it is for many other head-fi'ers out there
