Take a look at Altra. I've just got a pair of the Torin 1.5 and really like them - minimal but cushioned as I think you're after. Very comfortable fit, simple, no real arch support, zero drop, nice level of cushioning throughout the shoe.
I got mine mail order from Northern Runner and they seem to fit true to size - i.e. I'm a 10 in everything else, and was in these too.
Agree with book trunk 100% - if they work for you, stick with them.
But don't worry, the shoe manufacturers change your favourite shoes annually so there's a pretty good chance the shoes that work for you today will morph into something that doesn't in version 11 or 12. Then you'll have reason to find something new...
We've just had a Sweatshop open here so went in to find new shoes. Was told they did a free gait analysis, which quickly became an insole fitting session. I told the guy I wasn't really interested and that I'd tried similar things before but never really liked them (they change the fit of shoes - make them too small), but he said there was no obligation, so went with it.
I don't know if they'd have refused to let me try shoes on without going through the process, but they never mentioned cost - in the end I asked and it was £45.
When they were done, they put them in the first pair of shoes, I told them I didn't like them and he put them to one side and we got on with finding a new pair of shoes. Overall just proved to be a waste of time.
I have to say I wasn't overly impressed with the level of knowledge of the person serving me - made some very strange observations on shoes and technology. I would expect more from Sweatshop.
That said, I have 30 days to try my new shoes and change them if they're no good. That seems a pretty good deal to me.
