Cynosure · Aesthetic Lasers · $18,000 – $35,000
Unit condition and handpiece hours drive the delta - under 500 hours cumulative use on the main 1064 handpiece sits at $32K–$35K; over 1,200 hours drops you to $18K–$22K because the rod's near end-of-life and you're looking at a $4,500–$5,200 replacement. Service records from a known dermatology group sell faster than clinic shutdowns with gaps.
Pop the handpiece connector and eyeball the optics for internal crazing or soot buildup - that's a $2K repair minimum. Pull the service logs and cross-check against serial number on Cynosure's portal; forged maintenance history kills deals hard. Run the chiller through a full cycle for 10 minutes and listen for compressor rattle - replacement chillers run $1,200–$1,600.
California and Texas markets are oversaturated with RevLite SIs; Florida dermatology groups are hunting them aggressively because MedSpa chains shuttered post-2023. Schweiger Dermatology clinics in the Northeast still staff multiple units, so secondhand availability there is tight.

Yes, but run pigment first (lower fluence, 3–4J/cm²), then tattoo removal (6–8J/cm²) because tattoo ink absorbs more aggressively. Back-to-back treatments same day is fine; just wait 30 seconds between passes and let the cooling kick in.
1,000–1,500 hours before you see output degradation; after 1,800 hours the laser drifts and fluence drops 15–20%. Crystal replacement is $4,500–$5,200 and takes a field engineer 3–4 hours. Most clinics replace proactively at 1,400 hours.
Different tools. RevLite SI is pure 1064nm Nd:YAG; Excel HR is 532/1064 combo. RevLite hits black/blue ink faster on solo jobs, Excel handles multicolor better in one session. RevLite used market is $18K–$35K, Excel HR runs $25K–$42K used because it's more versatile. For tattoo-only clinics, RevLite wins on cost.

I save buyers 2–3 weeks of Craigslist fishing and eBay auction risk by vetting the PSU, crystal alignment, and chiller function before the unit ships - that's worth $800–$1,200 in avoided downtime. Plus, I know which serial number batches had 2019–2020 capacitor issues and flag those immediately.
