Hello Wil,
I have to mention (free) SQLd360 by Mauro Pagano as this is the tool that I use all the time:

... and then train your developers and DBAs in SQL tuning - especially in understanding what has gone wrong and how to avoid these issues in the future ...

IMHO all of these "automatic" tuning and analysis tools suck most of the time - especially if you just blindly follow and implement their suggestion without understanding the root cause.

P.S.: I can only agree with what Dominic wrote/said.

The background is that we have many complex SQLs being developed in our products, each developer may touch those SQLs and change them if he/she is handling a ticket related to them. Every change might cause performance changing (and actually they did). We want to find a tool can be easily used by the developers, and then give them a training session, they will be able to tune their new developed/changed SQL before tagged to the release.
