Go with what dave111 said, that seems to be the best price. It would probably cost around that to do a DIY hood... assuming you wanted some kind of Actinic lighting
. All thee above will allow you to keep Polyps, Shrooms, Xenia and most LPS.
And BTW most LPS are easy to keep along as you provide good water conditions, ample lighting and also some really seem to do much better when target fed.
