Candela · Aesthetic Lasers · $18,000 – $32,000
Units at $18K–$22K usually have 400–600 handpiece hours and clean service records; machines above $28K typically have <200 hours or recent factory refurb. That $6K gap reflects whether you're buying someone's trade-in or a clinic that aged out the device.
Check the cooling system first - run a test cycle and watch for uneven contact or leaking; that's a $2,500+ repair. Look at the handpiece connector pins under magnification; pitting or corrosion means heavy use and potential failure in 6 months. Pull the maintenance log and verify calibration dates within the last 12 months.
Southern California and South Florida dominate used GentleMax Pro supply because aesthetic clinics there upgraded to Cutera Excel HR and Lumenis M22 in 2019–2021. Texas is undersupplied and prices run $2K–$4K higher per unit.

Probably 4–6 years of clinical work if you service it yearly and replace the cooling cartridge at 500 hours. The laser tube itself doesn't degrade much; it's the handpiece and electronics that age. SkinSpirit clinics I know run 2015 units still - just budget $800–$1,200 annually for maintenance.
Yes, but sequence matters. Run 1064nm vascular first (lower fluence, less heat buildup), then switch to 755nm for hair. Most clinics do hair removal 80% of the time and vascular 15–20%, so the dual wavelength pays off.
Excel HR is newer (post-2015), has better software integration, and lower operating costs - but GentleMax Pro handles darker skin types just as well with the 1064nm, and your patient throughput is identical. You'll spend $3K–$5K more on a used Excel HR for maybe 10–15% faster treatment times. Not worth it if you're price-sensitive.

I source machines with valid calibration certs and under 500 hours; saves clinics 40–60 hours of downtime waiting for field service validation. Typical turnaround is 5 business days versus 2–3 weeks if you buy direct from a clinic without documentation.
