Lumenis · Aesthetic Lasers · $15,000 – $28,000
A unit with 400–600 handpiece hours and clean service records sits $22K–$26K; one with 1,200+ hours or a 18-month service gap drops to $15K–$18K because you're buying a rebuild ($3,200–$4,100 for new handpiece) risk. Rental eliminates that guessing game but costs you $2,600/month with maintenance included.
Pop the handpiece connector and look for carbon scoring inside the coupling - if it looks like burnt toast, budget $2,400 for replacement. Run a test pulse at 18mm spot on the metal test plate; if beam output looks dim or uneven across the window, the crystal is fatigued (fixable but $1,600–$2,000). Pull service logs and verify every single calibration date - gaps over 6 months signal neglect.
Southern California (Irvine, LA, San Diego) sees the hottest used Duet demand because Ideal Image and LaserAway have rotating trade-ups every 3–4 years and flood the secondary market. Texas chains in Dallas and Houston grab them fast because they depreciate slower than IPL units in that region.

No. At 40–50 sessions/week you're looking at $1,800–$2,200 monthly gross margin. Rent is $2,400+, you lose money. Buy used for $20K, own it in 10 months, then it's pure cash. Rent only makes sense if you're testing market fit or running pop-ups.
Every 1,000–1,500 treatment hours or 18–24 months of heavy clinic use. That's $2,400–$2,800 per swap. Budget $1,400/year as a reserve. Rental shifts that cost to the lessor, which is the only real advantage if you're low-volume.
Lumenis' lease is $2,900–$3,200/month with a 4-year lock and they own the upgrade path. Buy used from me for $22K, you own it day one, can upgrade or sell it in 3 years with zero penalties. Used = flexibility; lease = predictability. Pick your poison.

I save clinics 12–15 weeks of lead time versus buying new (Lumenis is quoting 16 weeks now on Duet orders). A clinic doing 90 sessions/week clears $3,200/month gross margin on hair removal - buying used at $24K instead of $58K new lets you hit break-even in 7.5 months instead of never.
