Unless the rules have changed, I have bought many pieces of equipment from corporations over the years and never paid sales tax. A sales tax is just that, a tax for a transaction between a buyer and a dealer or reseller (auction house) .Back in the golden days of commercial woodworking, variety saws like that were routine. The Delta Unisaw was considered a lightweight machine for trivial detailing.
As to the sales tax, its likely if that saw is considered inventory then it may apply. If it were being sold out of someone's garage, it would be a different story.
