MMV is one of the best single sets ever made for brickfilmers, it has many pieces, lots of figures, and a lot of tools/weapons. It has 1,601 pieces, 8 figures, 2 cows, a horse, a cooked turkey/chicken thing, and two fantastic buildings, and all for $100. BUT you better buy it fast, as it's all but discontinued. It doesn't have many special prints that restrict the parts use, and no windshields, laser cannons, or other hard to use parts, and....and...Wait, why am I trying to sell this to you? I would get that if you can, it's a great set.
As for the Robber's Hideout, unless you're planning on doing a lot of Cops and Robbers type of videos, I wouldn't recommend it. Yes, it has two rangers, two robbers, and is the cheapest set with the bear. But the set really can't be re-used well. It has some "brick-profile" bricks, and some of the 2X4 "Log" bricks, as well as some rock elements, but not enough of each to be much help in set-building. And then there's the car elements that can't really be used for anything but a car. And the piece count isn't that good either. If you're wanting specific parts or figs, Bricklink would be a lot cheaper.
But, I don't know what you're wanting with the set, so this may turn out to be perfect for your needs.
If not, then I'd at least wait until someone has it on sell.
