Candela · Aesthetic Lasers · $30,000 – $55,000
A unit with sub-1,500 handpiece hours and a service contract through 2023 or later sits at $48k–$55k; anything over 2,400 hours drops to $30k–$38k unless it's been recently retubed. One-year service gap or missing maintenance logs? Knock off 15–20% because you're buying a potential $8k tube replacement blind.
Plug it in and run test pulses on the test block they should have on-site - listen for the compressor cycling smoothly and watch the beam pattern for dead spots or uneven scatter. Pull the maintenance log and look for quarterly calibration stickers; if they're not there, assume the optics are out of spec. Check the articulating arm for play in the joints and inspect the handpiece window for pitting or micro-fractures with a loupe - cloudiness = failing optics = $2,400 replacement.
California and Texas are aggressive right now because med spas are consolidating and upgrading - Sona MedSpa and SkinSpirit are both hunting used CO2REs to fill out 8–12 location rollouts. Florida has cooled slightly because inventory flushed from 2022 bankruptcy liquidations is still circulating.

Dead tube shows uneven pulsing on the test block, weak beam at full power, or the unit won't reach spec wattage. Misalignment looks like a clean beam that's just shifted left or right - that's a $400 optical alignment job, not a $5k tube swap. Run it at 30W for 10 pulses and watch the pattern consistency.
M22 is IPL-based (broadband light), not true CO2 - different animal entirely, lower price ($18k–$28k used), way broader market appeal but less aggressive resurfacing power. Excel HR is fractional erbium, shallower penetration than CO2, faster healing, better for patients who can't take downtime - CO2RE is the nuclear option when you need real ablation.
If the unit is under 1,500 hours and fully serviced, 8–10% off is realistic. If it's over 2,000 hours or has a service gap, you've got room for 15–18% plus demand they eat any calibration work in the first 30 days. Don't go lower than that unless you're buying as-is with zero warranty - you'll lose money on repairs.

I handle verification calls with the previous clinic (cuts your due diligence time by 6–8 hours) and negotiate service gap coverage into the deal, which typically saves $2,000–$3,500 in surprise repairs in month two. I also know which serial number batches had tube issues - saves you from inheriting someone else's lemon.
