SP 540 Doesn't cut well--- might want to look into that before purchase. We have- and always a headache when it come to cutting sharp lines.
Ive never found that to be the case with either the 540 or the 300Does any one else find this?
For 114 bucks a month more over a 5 year period you could have a new unit that is completely redesigned from the ground up with many improvements, I say go new & don't look back, 5 years from now he used unit will be 9.
