Reading some blogs this morning, I found this article on SQL Server Performance Monitoring Tools.  The only product I see that they are missing is Red Gate’s offering, which I personally use.  But this is a great list as some of these I had never seen before. 

Does anyone have an opinion on these products?  I personally enjoy the Red Gate SQL Monitor, product, but it is the only product I have ever used outside of SQL Server itself.  Give me your input.  Enjoy!
