Cannot wait for the new Tascam DR-60 audio recorder to come out. This new unit has been specifically designed for use with DSLR cameras.
Check out this link for further information:
The unit goes on sale in the UK next month (May 2013) for a suggested price of £319.
It looks great with a lot of features for the money, including 4 track recording (in two stereo pairs), built in safety track, camera IN and camera OUT. LOVE IT :)
