I have a PTO Trac Vac on my 2210. Bought just the 3 point assembly used. Then added a Rubbermaid trailer. I guess have around $600 in it and it probably could use new hoses which will cost another $250 or so. But here are my thoughts, the PTO option is one less motor to maintain, and it is almost indestructable. The unit also has an 8" intake and exhaust, I think a lot of these other units are 6 or 7", so I rarely clog the unit up. I have a lot leaves, nuts and whatever, mostly all ends up in the trailer. Best attachment I own. $2500 for new one is a big investment, but something used can be a bargain. Right now is probably not the best time to buy though.
My 2 cents!
