3Shape · Dental Equipment · $22,000 – $42,000
A Grade A unit (under 2,000 scans, original calibration cert, tip optics pristine) runs $38K–$42K. A Grade C (5,000+ scans, calibration expired 18+ months, handpiece shows light scratches) lands $22K–$26K because you're replacing the tip ($340 each) and paying for recalibration ($800–$1,200) in your first month.
Open the handpiece and look for micro-scratches on the scanning tip under bright light - any visible damage means your first lab case will demand a rescan. Ask for the service log with specific dates; if you see a gap longer than 24 months between calibrations, the accuracy spec is theoretical only. Pull up the scan counter in the software before you buy - Trios logs every single scan, and over 6,000 means the optics are near replacement window.
California DSO markets (LA, San Diego, Bay Area) move these fast because Heartland Dental and Pacific Dental Services both standardize on Trios across their chains. Texas and Florida markets see longer hold times because independent practices still test Planmeca Voxel Brush before committing.

Yes, as long as your 3Shape contract is current. Updates are free and roll in monthly. Without a service contract you're stuck on whatever build was loaded when you bought it - usually 18+ months old by the time a used unit hits resale.
The camera module is field-replaceable but costs $2,600–$3,100 plus 90 minutes of tech labor. Most clinics just live with it or use monochrome mode and screenshot for shade - not ideal but workable until resale.
Run the self-calibration in software (Settings > Diagnostics) - takes 4 minutes and tells you if drift is under ±10 micrometers. If it fails or shows >15 micrometer variance, call 3Shape service immediately; DIY attempts void warranty and your resale value drops $3K–$5K.

I can move a Grade B unit in 6–8 days versus a clinic waiting 3–4 weeks for a new one from 3Shape with backordered chips. You also skip the 2-hour onsite training call ($600 value) because I deliver with basic software walkthrough built in.
