Kuhn sw1604 wrapper questions?

Hi guys I am waiting on a price for a kuhn sw1604 wrapper that does 3x3 squares and rounds as well and wondering if anyone on here has one? I am wondering how many bales an hour you can usually wrap and how long does it take to wrap each bale? Also how many bales would a roll of wrap do? Figuring on buying it to wrap bales for myself as well as wrapping for others, figured $8-$9 a bale would be fair to charge unless they use their own tractor and labor on it or am I out of line on prices? Tube wrapper around here is $8 a bale and your own labor to run it.
