Candela · Aesthetic Lasers · $18,000 – $32,000
Machines under $22K usually have 2500+ handpiece hours logged and may need cooling system service within 6 months ($1,400–$1,900). Boxes at $28–32K with under 1800 hours and recent calibration hold value better and skip the immediate repair debt.
Pull the service logs and look for the cooling system repair dates - if it's been 18+ months since last DCD maintenance on a high-use unit, budget an extra $2K. Inspect the handpiece connector pins for pitting (sign of electrical arcing); any visible corrosion means capacitor replacement is coming. Run a test pulse into a test load and check if the fluence meter reads within 5% of the display - if it drifts more, the laser tube is losing output.
California (especially LA and San Diego) has oversupply of used GentleMax Pros because Ideal Image franchises rotate equipment every 4–5 years; Texas and Florida are undersupplied and prices run $2K–$4K higher. Demand spikes in spring/summer when clinics restock before peak season.

Run it on a test block at max fluence. If the joules reading bounces around (variance >10%) or the cooling device cycles irregularly (should be smooth 30ms intervals), the tube is degrading. A clean handpiece reads stable. If it's erratic, assume you're replacing the tube within 60 days - budget $4,200–$4,800.
Not dead - different tool. The Excel HR has single 755nm, smaller footprint, and 200–250ms pulse width (better for fine hair). GentleMax Pro has the dual wavelength advantage and deeper 1064nm penetration for thick coarse hair and vascular work. Excel HR is $26K–$35K new; used GentleMax at $20K is the budget play if your clinic does 60%+ hair removal on darker skin types.
87% uptime = roughly 2.5 hours down per 20-hour week. That's one missed treatment slot per day. Acceptable only if your clinic has a backup (IPL or diode). If this is your only hair removal machine, you need 92%+. Sona MedSpa runs single GentleMax units and they negotiate service contracts with 24-hour response; costs extra but keeps them live.

I save clinic managers 40–60 hours of vetting and negotiation per machine by screening handpiece hours, cooling system history, and alignment calibration upfront. That translates to money - getting you running in 2 weeks instead of chasing vendors for 6 weeks costs you real patient revenue.
