Planmeca · Dental Equipment · $3,500 – $7,000
Sensors under 2 years old and calibrated within the last 12 months run $5,500–$7,000; anything older or showing pixel dropout or cable strain runs $3,500–$4,500. Service history gap over 18 months tanks value because recalibration cost is $600–$900 and you can't trust sensor accuracy until it's done.
Pull the sensor housing apart at the seam and look for white corrosion on the circuit board - that means saliva got in during sterilization and the sensor's done. Check the USB cable connector pins under magnification for green oxidation; replacement cables run $120–$180 and shops charge $85 labor to swap. Ask the seller for the last calibration report by date - if they can't produce it dated within 12 months, walk or drop your offer $1,200.
Southern California DSO practices (Los Angeles, Orange County, San Diego) are rotating stock every 3–4 years as they standardize on newer Planmeca Proxi or Vatech sensors, flooding the secondary market with 2019–2021 Intra units. Texas (Dallas, Houston) has less turnover but higher wear from high-volume clinics, so expect more sensor pinging and cable issues.

Buy. Period. At $310–$380/month lease, you're at break-even in 12 months and the lessor keeps the sensor if it fails after year 2. A $4,200 used Intra with full calibration is yours forever, and if it dies at year 4 you replace it for $3,800. Independents I work with own two and rotate them through sterilization.
Planmeca Intra sensors fail at about 8–12% per year past year 3 of use - mostly cable disconnects and pixel dropout in the bottom corner of the active array. Repair through Planmeca service is $520–$750 plus $120 shipping; local techs can reflow solder joints for $280–$400 but that's a 50/50 gamble.
No direct warranty from Planmeca on used units past the original owner - you get my 90-day functional guarantee. Sage Dental and Heartland Dental both self-insure used equipment and just factor a $600 replacement reserve into their acquisition cost, which is the right move.

I place these in bulk for DSO roll-outs and negotiate factory recertification at $400 instead of retail $850 - saves a clinic chain $2,100 on a 10-unit order. On the lease side, I've cut 3–4 clinic managers' monthly costs from $420 to $310 by switching them to buy-now financing through Patterson or Henry Schein at 6% over 36 months.
