$113 - Yongnuo YN-565EX Flash - ebay
or at DX - $114 - YongNuo Y565EX 2.0" whilst this listing shows the full (bewildering !) Yongnuo flash range.
[color="Gray"]Anyone used one of these ?
The Yongnuo 565-EX released a few months ago seems to be feature-packed, and a good value alternative to Canon/Nikon's own, at about £100.

The YN-565 competes with Canon’s 580EX II and the Nikon SB-900, but also with other 3rd party flashes in the professional class. Contrary to first rumors there’s no wireless master mode (commander mode): the YN-565 can be controlled by another commander flash (in the same way that Canon’s own 270EX II, 320EX, 430EX II and 580EX II can be controlled) but it does not have the ability to control other flashes itself. If you need a wireless master flash look at Canon 580EX II, Nissin Di866 / Di866-II, Metz 58 AF-2, or maybe at the Sigma EF-610 DG Super.
ФAWL SUPPORTED FOR N’s & C’s SYSTEM - The YN565EX can be triggered by 580EX II, SB-900/800/700, 7D/60D/600D, Nikon c-command and ST-E2, and flashes as TTL mode as well as M/Multi mode. To enjoy wireless TTL lighting, ratio control, as well as remote control of output level, you may only take a camera with built-in commander mode, and the YN565EX.
