Acteon · Dental Equipment · $3,000 – $6,000
The $3,000–$6,000 range splits hard on handpiece hours: under 3,000 hours (light clinic schedule) lands $4,800–$6,000; over 5,000 hours or any gap in service history drops you to $3,200–$4,200. A documented handpiece replacement in the last 12 months is +$800 to your asking price because buyers know they're not inheriting a worn bearing.
Pull the unit on and look at the footswitch cord - cracks or hardening mean the pressure switch is next (happens around 4,500 hours, costs $380 to replace). Listen for a grinding sound during a 30-second run with no water; that's internal cavitation issues and it's a $1,100+ repair. Ask for the calibration logs from the last service visit; if there's no paperwork, the machine wasn't serviced and the seller is hiding something.
Southern California (Irvine, San Diego, LA metro) has constant demand because Heartland Dental and Western Dental rotate equipment every 5–7 years and dump their P5s to brokers - turnover is predictable. Texas and Florida are slower; those big chains use captive purchasing and rarely release gear to the secondary market.

No. They're peers. Piezon Master runs 30 kHz (slightly more aggressive), costs $500–$800 more used, and has a smaller insert ecosystem. Pick the P5 if your clinic already stocks Acteon inserts; it's not a quality difference, it's logistics.
Mostly Acteon and EMS - they're cross-compatible on some models. Third-party generics exist but they're garbage; they vibrate loose and chuck the insert mid-procedure. Buy the real insert for $280–$320 and move on.
Cavitation pump failure (sealed unit, can't repair in-house, $1,100+) and footswitch pressure sensor death ($380). If the power control dial feels sticky or doesn't hit max output, that's the beginning of the end - walk away or price it at $3,000 and hope.

A unit with clear service history and sub-4,000 handpiece hours moves in 8–12 days versus 40+ days for an orphan unit with no paperwork; that's the difference between your floor carrying cost eating margin. A single sheet - service log, handpiece hours, last repair date - can add $900–$1,200 to your sale price because it erases buyer risk.
