Check out 'The Chemical Brothers - Live At The Social Volume 1'. It's a really good old skool mix from the Brothers.

'Prodigy - The Dirtchamber Sessions Volume One' is somewhat similar in style to the Chem's 'Brother's Gonna Work it Out' CD. It came out around the same time ('99), features current songs of the time as well as old tracks, and has a lot of quick cuts and overlapping tracks.

Another interesting one is 'Kill The DJ: A Non-Stop Mash-Up Mix By Keoki'. It is a fast paced mix combinig an electro feel with new versions of retro tracks.

I'm sure a lot of posters here will also point you to the 2 Many DJ mixes by Soulwax, but I'm not sure which one to recommend.
Crystal Method released two mix CDs titled Community Service and Community Service 2. A lot of people seem to like these. The track selection and mixing are cool, but they don't have quite the same energy as the others I've mentioned.
Adam Freeland's mixes are also always good, but I think I prefer some of his live stuff to his studio mixes. His 'Coastal Breaks' series was very popular.
If you like Electro, there is a Dave Waxman mix that is pretty cool. The mix is pretty straightforward, but the song selection is great.

If you're into trance, there is also 'Communicate' by Sasha and Digweed, 'Perfecto Presents Another World' by Paul Oakenfold, and 'Tranceporting 4' by Max Graham. I can offer more trance recommendations if you like these.
