I bought an OS35 with 2 extensions and the mobility kit and the hydraulic kit. It was about $18k not including financing costs. The hydraulic kit is very new, so there are early product issues that all companies must correct. The people I spoke to are nice but you can tell that the management isn't really thinking this product out very well; the manuals and the lack of thought with the hydraulic kit and the trailer kit is very evident. Would I buy it again? Yes. What will I do for my next mill? I will build my own. I will get more experience using this one and I will build my own. You can't finance a homemade sawmill or any other type of machine, so I had to buy a factory made one that I could afford and it needed to be big.
