Please... say Electronica... Techno refers to a specific genre of dance music that's a very specific sound. What you listed was Trance mostly, and if that's what you like, check out anything with the following names: Paul Oakenfold, Timo Maas, and DJ Tiësto.

House: DJ Dan is a good bet. So is Dave Angel (More techy/detroit) and Hardfloor (awesome tech house)

Happy Hardcore: The Happy2Bhardcore CD sets are like a standard for this scene. Cloudskipper and DJ Tronic kick some ass too...

Techno/Electro: Westbam and Takkyu Ishino are the shit. Benny Benassi and Dirty Vegas are also good

Drum n Bass: Good artists are Aphrodite, ak1200, and Dieselboy


That being said, I have an awesome hour long mix from the Loveparade 2000 with Carl Cox, Westbam, and Paul van Dyk... rawkin set that flows from progressive to electro to techy trance... excellent .mp3 ... Westbam really tears it up too!
