Personally I don't mind paying for the shipping, especially if the item is out of warranty or if the servicable parts are wear-and-tear items.
Tools will wear if you use them, no big deal. I don't expect a sawblade to be sharpened under warranty, and in my opinion, the same goes for a lot of other parts as well. Premature wear is another ballgame, and I would expect my dealer to step up for me when this occurs.
It's just that I like the dealer to take the hassle out of the whole servicing process, regardless of who pays for the parts and/or shipping in the end.
My dealers ( actually I frequent two Festool dealers ) do just that. They know I'm capable of servicing tools myself, and order parts whenever shipping a tool back and forth isn't required. When I'm in a pinch I needn't be without a tool, for they'll lend me one. Then again, they know I won't ask if it isn't necessary - these things go both ways.
That's what I consider decent service. I definately need it too, for over here the local Festool subsidiary isn't really keen on dealing with mere end-users, if you catch my drift. Really great guys that will go to all lengths if you meet them at a tradeshow, but apparently in day-to-day business dealing with end-users doesn't fit in the company policy - so be it.
You guys at the other side of the pond face a somewhat different situation, as it seems. Festool dealers few and far between (compared to my situation at least) and apparently a slightly different culture regarding service issues.
But then again apparently there's a good deal ( no pun intended ) of Festool dealers that seem to be willing to walk the extra mile and even a couple beyond that to keep their customers happy, and when even Festool USA's CEO steps in to iron things out, that's kinda special. I may be wrong, but somehow I don't expect HILTI USA's CEO to do just that

All in all I think most professional users have reason enough to be happy with the way Festool is in touch with their customerbase. Infrastructural limitations apply, but given enough time (say 5 to 10 years ?) I wouldn't be surprised if people would begin to quote "Festool" next to "Hilti" or "Caterpillar" as a reference for top-of-the-line service.
Just my take....
