yeah, you have to have a really BIG one to get through a decent amount of work done.Doesn't make sense to me. Too bad. A missed opportunity for you but I hope you can find a free source of wood chips.
Although I have a smaller electric wood chipper (up to 1.5 inches) and a larger, more powerful gas chipper (up to 3 inches), I would not recommend investing in those wood chippers if you can find wood chips for free. I still use my wood chippers at home for lawn cleanup, but it takes a good amount of time to chip up wood at home. The people who sell you the chippers make it sound like it's no work at all. But I can load up my trailer full of free wood chips at the county landfill in 15 minutes that would take me about 10 hours of chipping wood at home.
Instead of chipping up my fallen branches, etc... lately I have been cutting them up with my recip saw or chainsaw and tossing them into my new hügelkultur raised garden beds. It's a better way for me to use up those branches then spending all that time chipping wood now that I have a source for free wood chips already chipped up. Sometimes I cut down a tree and have to burn out the stump. So, that is another good use of those branches. There are lots of ways to use up that wood and I have not hauled out any branches to the landfill in over 20 years. My goal is to keep and use all organic material on my property as best I can.
Those little chippers are for clean yards. Like a roomba and swiffer are for clean houses.
I get you on using the sticks in different ways.
and I dig (LOL, not yet) the hill bed thing.
