Like Toban, I bought Site Build-It and I didn't like it either, so I asked for a refund and they were true to the word concerning the money-back guarantee.
I'd agree with Toban that it's not very good, even for newbs. Site Build-It sites tend to look the same (very outdated and non-Web 2.0), and even if they work on some level, they promote quantity over quality. Moreover, I had technical difficulties with publishing, and they couldn't solve my problem. That said, Steve is very up-front that it is good for newbs, and though I consider myself a newb in this area, if other newbs swear by it, he's probably right.
Personally, I like SquareSpace for easy website development and hosting (plans start at about $8/month -- pm me and I'll give you a referral link
), though there are plenty of free alternatives. The alternatives might not help you make the type of copy-cat, high volume sites that Site Build-It seems to promote, but they can help you easily make very attractive sites with easy to use WYSIWYG (What You See Is What You Get) editors. Webs.com and Weebly.com spring to mind.
