| Demand/Resale Value*** |
$$$ | $$$ | $$ | $$ | $ | $ |
**Similar devices are manufactured by vendors other than the linear accelerator manufacturer
***Five $$$$$ indicate that the resale demand for like systems is high, and used equipment will therefore command a higher price
Few dollar signs indicate that the resale demand is lower, and prices for used equipment is lower. One $ indicates very little, if any, value currently exists.
