What's Up Gold & Singlestep Unity

I currently work for a company developing interfaces and policies for their network using WUG and Unity. I was wondering if anyone has had any experience with either program. Advice, opinions and comments are greatly appreciated.

Sorry, but I can’t bring myself to use something that cost’s money, when there is already a great free product with plenty of support. Kinda like using Redhat enterprise rather than using CentOS. Why would anyone do that? Sorry, I just had to add my $.02, and good luck in your search.
