Dentsply Sirona · Dental Equipment · $25,000 – $45,000
Used Omnicam units with under 4,000 milling hours (roughly 18–24 months of moderate use) hold $38K–$45K; anything over 6,000 hours drops to $25K–$32K because spindle wear becomes real and you're looking at $2,100–$2,800 rebuild cost. Service history gaps (no maintenance records for 6+ months) knock another $3K–$5K off asking price because nobody wants a mystery box.
Pop open the milling chamber and inspect spindle bearings for play - grab the chuck and wiggle it side-to-side; if there's movement beyond a mm, spindle is shot and you're replacing it. Scan a test crown from included calibration block and compare file size to new Omnicam scans (should be nearly identical); bloated files mean optical sensor is degraded. Run the spindle for 30 seconds and listen for grinding noise or vibration in the 2,000–3,000 rpm range - that's bearing failure talking.
Southern California (Irvine, Long Beach, San Diego) sees heavy Cerec turnover because three major DSOs run fleets of these and trade up every 4–5 years - creates used inventory but also drives realistic pricing. Texas corridor (Dallas, Houston, Austin) has younger practices still buying new, so used units move slower and sit 60–90 days before pricing drops.

Buy used. Lease is $1,400/month all-in (scanner + milling), that's $16,800/year. You'll own a solid unit outright for $32K–$38K in 2 years, then you run it another 3–4 years debt-free. Heartland Dental does the math this way internally and buys every time for sub-15-crown-per-week clinics.
Spindle failure runs 8–12% on used units over 5,000 hours; replacement spindle assembly is $2,100–$2,800 plus 4–6 hours labor at $120/hr. So worst case you're paying $3,000–$3,500 to resurrect a $35K unit. That's still cheaper than five years of $1,400/month lease payments ($84K total).
iTero mill-in-office is a year away from real traction; most Align shops are still outsourcing milling. Omnicam wins on speed (4–6 min mill time) and on file reliability (Sirona's proprietary block database is rock solid). But if your lab partner has iTero integration already built in, switching costs kill the deal - stay where you are.

I source units directly from DSO trade-in programs, so I skip the dealer markup and land deals $4K–$8K below retail brokers asking for the same unit. That $6K average savings funds your first 4 months of software updates and calibration checks, which you're doing anyway.
