Been looking at this monitor, trying to price out what a complete "kit" would cost. . .case, batteries, some kinda arm to attach to cam, sunshade. A cheap battery option by CD themselves was mentioned in another thread last year. . .did that ever come to fruition? I don't see anything like that on B&H's site, Nebtake 2 batt cage for Sonys seems to be the cheapest one on there, and that's almost $300, and then of course you'd need the batts themselves. Wondering if I'm missing anything. Thanks.
