Aribex · Dental Equipment · $4,000 – $8,000
A unit with sub-500 tube hours and annual service records documented runs $6,500–$8,000; one with 1,200+ hours and a 3-year service gap drops to $4,200–$4,800 because you're buying a tube replacement ($2,100–$2,800) and calibration whether you admit it or not.
Pull the tube hour counter from the digital display - anything over 1,500 hours means the tube's in its last 12–18 months of life. Check the battery charge/discharge cycle count in settings; if it's over 800 cycles, replacement is $180–$220 and imminent. Inspect the cone tip seal where it meets the tubehead; hairline cracks there leak radiation and cost $340 to replace.
California dental groups (especially PDS operatories in the Bay Area) rotate out Nomad Pro 2s every 4–5 years because compliance tracking is easier than field repairs; Texas market moves slower, which means more used inventory and lower pricing by $600–$1,200 compared to coastal markets.

OEM service contract through Aribex runs $320–$480 per year depending on whether you bundle tube hours. That covers calibration, battery test, cone seal inspection, and parts discounts. Most clinics skip it and eat the $140 calibration fee when something drifts - math doesn't work in their favor.
Battery fails first (8–10 years typical life), then the tube (1,500–2,000 hours), then the handpiece trigger switch. The battery replacement is DIY, $180–$220. The tube is $2,100–$2,800 and requires Aribex certification. Pacific Dental Services standardized on replacement batteries at year 6 across their fleet because the labor cost of field repair exceeds parts cost.
Third-party batteries exist and run $90–$140, but they void your calibration cert and regulatory compliance can be questioned in audits - not worth the $100 savings. Stick OEM or don't bother.

I can source OEM replacement batteries, cones, and tube assemblies direct from Aribex at 22–28% below retail clinic pricing - that's $240–$480 per unit depending on quantity. That saves a clinic $1,200–$1,800 annually versus buying piecemeal from their dental supply rep.
