Hi Jeffro
I use XAMPP for local installs and have looked at ServerPress a few times.
The only problem is that ServerPress and XAMPP can't be run together so I'd have to move all my XAMPP sites over to ServerPress.

I understand that at the moment there is no automated method of making this changeover so for the time being... I'm staying with XAMPP.

If anyone knows of a painless way of making the move I'd gladly buy the premium version of ServerPress.
