I agree that those machines will do the job, but then again, for how long til they're worn out? I live up on Puget Sound and have had a BU come through my hands that was worn out from sail making. Though to be fair, who knows how many years it was fed this diet? It could've been many years.
I also agree that low cost industrials can be found if you're patient and know what you're looking for. My Consew mini walker was brand new and cost me less than 2 fast food meals. I dropped it on its back before I got to use it.
