@MikeAqua: Thanks for all that! Yeah, I'd heard over and over that for any saw apart from the really pricey ones the first thing you do is replace the blade and, for table saws, the mitre gauge. The reviews of the Skil pointed out its ability to take a dado stack but the only time I've needed something like that was for trench cuts which I did with the mitre saw, same with pretty much any mitred cuts which I'd do with that. For the bad dust collection, I already haul the mitre saw outside to the patio and run it there (so the neighbours can appreciate the work as well) so it's not a major consideration.
So I'll go for the B&D, I watched some video reviews of the Skil and while the rack&pinion fence is much nicer than the slide-and-clamp style on the B&D and others in its price range I can't really justify paying twice the price just for that. It does look like really good value for money otherwise with lots of nice features but it's still twice the price.
