Midmark · Dental Equipment · $7,000 – $15,000
A chair with under 8,000 cumulative hours and zero service gaps in the last 24 months runs $12K–$15K; anything over 12,000 hours or with a gap of 6+ months since last maintenance drops to $7K–$9K because you're inheriting unknown hydraulic wear.
Sit in it yourself and pump the foot control five times - if it's mushy or sticks mid-travel, hydraulic seals are going bad ($800–$1,200 to replace). Check the backrest memory foam by pressing your hand into it; if it doesn't spring back in under 3 seconds, foam degradation means sagging chair in 6 months. Pull the service records and look for the last seal kit or O-ring replacement - if there's nothing in the last 3 years on a 10,000+ hour chair, the seller's hiding something.
California and Texas drive used Midmark demand because Sage Dental and Western Dental are consolidating older locations and liquidating chairs in bulk. New York and Florida also spike demand when DSO practices upgrade to newer models mid-year.

Planmeca runs about $18K–$22K used and has integrated digital imaging arm mounts; UltraComfort is $7K–$15K and pure ergonomics. Planmeca wins if you need iopan imaging in the chair, but UltraComfort wins if you want reliability without the tech bloat.
Look at the vinyl seat - if it's cracked or stained beyond normal wear, that clinic ran 50+ patients per day. Check the foot control joint for play (wiggle it side to side); loose play means 15,000+ hours of wear and hydraulic fatigue is coming.
Yes, 10–15% off is real if you catch timing right - end of quarter, consolidation sales, or a seller with two chairs and only one buyer. But if the chair's under 8,000 hours with full service records, don't lowball; you'll just piss off the seller and lose the deal.

I can source a three-chair package from a closed clinic location and negotiate $2,000–$3,000 off per unit because sellers move fast on bulk deals; buying one retail through a dealer costs 15–20% more. Most brokers take 45–60 days to close; I move inventory in 14–21 days, so your operatory stays live instead of dark for two months.
