Edger help: What is a good Used Edger to purchase from Third Party?

[jcxover2]

We have a practice that cuts 30 jobs a week. We had a Briot Accura Edger and Santinelli 9000SX in the past. We mostly cut Poly, Cr-39, HI : Single Vision. We groove occasionally. No need for drill mount (we just send it out to local lab). Any suggestions on which manufacture edger to purchase.

Factors include:
Dependability,
Parts and supply availability
Phone support ( I know Santinelli requires recertification),
Cost for on-location repairs by their service techs.

Thanks for your feedback.
