300M timing belt: it's time -- but where?

Our 300M's timing belt is now due for replacement, but I am wondering
how much difference it makes where I have the job done. I am planning to
have the water pump, tensioner and pulley replaced all at the same time.

The single-location Chrysler dealership where we had all our service
done during the 6+ years we've lived here is no longer an authorized
dealer but advertises that they still have all the special tools.

Not far away is a multi-location (two-state even) dealership -- still
authorized -- with which I have had no dealings at all.

There are independents of which people speak well. If I went to one of
those I would specify genuine Mopar parts -- at least for the belt and
tensioner.

Any recommendations? Obviously the vehicle is no longer in warranty, but
are there any relevant TSBs about which an independent or a delisted
former dealership might not be aware?

most all the shops out there have access to alldata and Mitchell's so i
don't think TSBs will be a problem. if the shop that's worked on it before
still has the tools, then they might still have the same personnel too. are
they now just an independent? or did they switch to selling some other
brand? did their labor rates change since they are no longer "authorized"?
