Just been looking on the Argos site for a Digital Camera and this came up. You get a spare battery, case and tape. It is compatible with the VP-D371W and VP-D375W camcorders.
Having had a quick butchers online a spare battery is £11 or more plus postage. So for an extra few quid you get a nice case for your camcorder and a tape too.
I appreciate tape camcorders are few and far between but I'm sure this will be of interest to some people.
