Estimating the Size of a Table in SQL Server 2008

I have read this (http://msdn.microsoft.com/en-us/library/ms178085.aspx) article at least 6, maybe 7 times in the past - and every time I say to myself "this is ridiculous - someone has to have written a script to do this by now" and every time, I google for hours and fail to find anything. So I finally gave up and wrote something to do it. Note, I've only verified it on 100% fixed width tables. I compared its output to a 600+ million row table and it came out somewhere around 3% higher - fine with me as I'd rather over-estimate space requirements than under-estimate.
