I am using MTS for several months now, and I can recommend it to anyone, who wants to get fine and quick results.
My experiences are, that it is possible for users, who don`t have the knowledge or the time to make changes in the source code, to have a lot of fantastic results using MTS regarding design and usability.
The support of George is fast and very good. You don't have the feeling, that you are alone, if something doesn't work.
