Where did you find a Catalyst for $190? With good wood, the Cat should last you 5+ years. The refractory assembly, based on what I can see, looked to be in decent shape. It could last 3 years. Maybe more. So, for $258, you've given yourself at least three years to save up for the stove you want. In the mean time, you will have a stove that will give you 8-10 hours of heat. Sometimes more. They are a pain in the ass to maintain. But, in good working order and installed correctly, they provide a lot of heat, steady temps throughout the burn, and good burn times.
