Having used SQL Compare for a couple of years now out in-the-field, I'd agree with your observations Robert. It is an excellent product, very stable and does what it is designed to do very well - I've recommended it to a number of people. It's very good at sorting out the problems experienced by development teams who've not had the know-how to keep dev. and test / production databases in sync. Well worth the money.
