The EH Rippers were awesome kites, pretty much the holy grail of C kite feeling with bow kite usability, relaunch wasn't great on the early ones but still great kites. Never really that popular though
GK Sonics still rock, the 06s tended to fall apart and were a bit quirky but the 07s were well built - maybe not great at everything but for lighter winds and boosting they are still up there with the latest kites.
Naish Torches, I have a 2007 10m that I still fly and would be flying a 07 12m if it hadn't worn out - also got 08 8m, 09 6m, 2010 12m and 07 14m - they still perform better tha a lot of modern kites
As for the Waroo - maybe not the 06 but the 07 is still a kite that is rideable against today's kites.
