Acteon · Dental Equipment · $3,000 – $6,000
A unit with clean service records and under 2,000 handpiece hours sells for $5,000–$6,000; anything north of 3,500 hours drops to $3,200–$4,000 because piezo degradation is real. Missing maintenance records or visible water staining around the footswitch will dock $500–$1,000 off the asking price.
Pull the handpiece and check for white mineral buildup inside the tip hole - that means inconsistent water flow and you're buying a $1,100 service call. Listen for grinding noise when you cycle the foot pedal without water; that's the coupler bearing going bad. Ask the clinic for the actual maintenance log with dates and tech names, not just a generic "regularly serviced" story.
California DSOs are selling used P5 units constantly because they upgrade to newer Acteon models every 4–5 years; Texas and Florida markets move slower, so you'll see 2–3 month older inventory there. Irvine and Orange County clinics dump these units when they refresh operatories, which is why I see three units a month here versus one every six weeks in Dallas.

Yes, if you service it every 500 hours. Heartland Dental runs these machines 35–40 hours per week and gets 4.5 years out of them. Miss servicing and the ceramic impeller cracks around year 2.5, then you're replacing the whole water system for $900–$1,200.
Lease at $200/month equals $2,400/year. Buy at $4,500 and you're ahead after two years, even factoring in a $1,100 service call. The lease wins only if you want zero maintenance hassle and plan to upgrade every 36 months; that's a Sage Dental or Pacific Dental strategy, not an independent clinic strategy.
The P7 runs 42 kHz instead of 32 kHz and has Bluetooth foot pedal integration; you'll spend $8,500–$10,200 new. Used P7 units are $5,800–$7,200 and faster, but the clinical difference is maybe 3–4 minutes per patient. If you're price-sensitive and patient volume isn't maxed out, the P5 is the correct buy.

I handle the shipping ($380–$550 depending on destination), verify the piezo stack with a basic frequency test before it ships, and negotiate warranty terms with the selling clinic so you're not inheriting mystery problems. That saves you 6–8 hours of your own troubleshooting time and keeps you from buying a lemon that costs $1,500 to fix.
