Just so you know, many of the Red Gate softwares are licensed per user. This means, as long as it is you using the software, you can install it on more than one machine. Prior to working for Red Gate, I had their stuff installed on three different machines, but they were all mine. I was the only user, so it was perfectly legal.

If that helps.

Personally, other than monitoring tools from other vendors, I never found anything compelling enough to use on a daily basis except for the Red Gate stuff. Mladen's software is the one exception but you already have that listed.
