just wanted to let everyone know that I have successfully setup the VHCS control panel on a Spry WebMin VPS with success..
VHCS is a great (free!) control panel licensed under the Mozilla Public License 1.1 (MPL 1.1)
Should be a good option if you dont want to pay for a control panel.
There is also a fork available under the name of ISPcp, but I have never tried it, and there are no stable releases.
VHCS: www . vhcs . net/
ISPcp: www . isp-control . net/
(sorry for the way the URLs look, but the forum software wouldnt let me post the URLs otherwise)
