Well, you have to factor in the HF (& craftsman) router tables run ~$100 and they come with the router and pretty much everything you need and you can easily get them for less than that.
The routers are not great, that's for sure, but for the price you're not really going to get a router and make the table and the legs and the split fence and fashion a bit guard w/ attachment for some dust extraction, which is absolutely necessary or the dust will kill your router in no time.
Like I said, depending on what you need to use it for, they can serve a purpose worth the cost. IIRC I actually got the Craftsman one for $60 or thereabouts with rewards points and I mainly used it just to help make my current router table. It was one of those, I needed one to make one, kind of things.
