Thanks for your input everyone.
I agree with all of the above, my only issue is that the 664 doesn't record internally and only has AA batts as a backup if my NP-1 dies during a shoot. Especially since I do alot of run and gun reality tv
I am new to this forum and was just curious on everyone's thoughts on this topic.
I work with the 788t on a regular basis and was thinking of possibly purchasing a 664 to add to my kit.
Thanks in advance!
