There is no need to pay $20,000-$30,000 or more for a therapy laser. The laser diodes and optical fiber cables that all diode laser manufacturers use are practically identical in design and origin, and wavelength and power levels are all in the same range. Only empirical evidence exists to suggest that multiple wavelengths, ultra-high power levels, built-in protocols, and glitzy control screens are beneficial to the patient. In reality, those items are extraneous, and do nothing to increase patient response to the treatment provided but are only effective in separating doctors from their hard-earned money.
