I'm looking for an easier way of deploying multiple solutions. I know I can write some scripts which handle all my WSP packages (both install and uninstall), but I want something more automated.

Also, I will be distributing some of my solutions, so a nice UI would be good.

I found SharePoint Solution Installer on codeplex, but it seems to be outdated and I still need to configure it manually. I also tried Advanced Installer. It's easier to use and has a great UI, but it's somewhat expensive.

Are there other alternatives? Or do I need to pick one of the above?
