Yeah - I've used one of those websites before. It was painfully slow to load, and if the sites not public yet, you can't use it.
The problem with testing on your own PC was that browsers only lets you have one version installed. But now there is multipleIEs (I think it's called) which lets you load up multiple versions of IE, safari is released on PC, and PortableApps has Firefox (all versions) which now makes testing a lot less painful. (Don't bother with FF 1.0 - it's a dog, and anybody who used it was bleeding edge, so have upgraded.)
BTW: microsoft have "warmed up their photocopying machines" for IE8 and made a virtually identical firebug clone. Except it's not buggy as hell. It might upset the firebug developers, but I think quite a few people may move to IE8 for javascript development once it gets out of beta. Now they just need to have the guts to lie about their user agent ("Internet Explorer" triggers various kludges on a lot of sites, which pushes ie into quirks mode), encourage some plugin developers, and I think IE8 could become the best browser out there. (Clarification: I am not a fanboi - microsoft has no fanbois.)
