I've been using FinalBuilder for almost a year and I think it's a great product - in fact I find it hard to use others tools.
One other point of pain I have at work is installer, we use WIX and edit it's XML by hand or by using WixEdit and its hard and furstrating.
I wish there were a tool similar to FinalBuilder that I can create MSI (or wix file) from - it would be a great time saver both from creation and maintainence.
Istallers should be that hard - and perhaps VSoft can get us there
