I've got an older version of this one

It's pretty much the same.
As long as you accept its limitations it's great. We have an area of our property that power lines run through and we keep it clear so the power company doesn't send in contractors (different ones every time who do different things). I chip a lot of the branches from the saplings we cut down every few years. I find the leafy ends of the branches can bog down the machine - it's not great with leaves and small twigs. I trim the smaller branches off the main branch on some of them and keep those bare branches for running through after every few leafy ones to clear the blade. Leaf gunk builds up and bakes on to the blade and near the end of a chipping session, the small twigs aren't getting cut well and start wrapping around the blade, requiring many stops to open the thing up and clear it out. It's quick and easy to do, though. In between uses, I scrape the leaf gunk off with a razor blade. I usually do a big pile all at once and it takes me three or four hours. The last hour or so is when it starts getting annoying with clogs. Dry branches don't really have the same problem.
The feed opening is really small. It's shaped kinda like a barbell when you're looking down at it, two round holes joined with a slot. The holes are a couple inches across, just big enough for the plunger. And all the openings are covered by flaps of rubber, so you can't really put leaves or small, loose stuff through it. Someone I know has the same one and chopped the rubber flaps off and enlarged the opening so he can just chuck whatever down. He works it pretty hard, probably harder than I do mine in some ways and he's had his longer, too.
It sounds like a little electric one would probably work okay for what you've got in mind. If you're doing lots of small branches all at once, have something else to run through occasionally to keep the blade clear.
