Go the llc route. Remember that even if you have a lot of coin drop, you will have depreciation to offset this, plus I'm sure there will be other expenses along the way. You can take section 179 depreciation, which is basically expensive the entire amount of the machine in the initial year , as long as it doesn't create a loss. Or you can take bonus depreciation, which can create a loss, but isn't a 100% deduction in the initial year. Also, this income will most likely be passive so the losses would would be suspended unless you have passive income to offset against. Get your insurance and cover your ass. Saving a few bucks isn't worth it.
