I have six rotarys, a jeiber I bought off ebay newa couple of years ago, very good value for what I got with it, two drive boards, two brushes one soft one stiff and it has a chemical tank and a box of red pads, two dry fusion machines, a Chemspec rotabrite machine which is 21" with sprayer and my trusty Chemspec Chemstactor, out of which is my firm favourite, 175 rpm the right weight and ballance and with its ten litre chemical tank and the sprayer in front of the machine its ideal for encapping
I did ponder about the possability of getting a orbot but dont think it would match the cleaning power of the chemstactor, only pity chemspec stopped selling the original type which were the best by far
