I saw this stove for sale. I've owned two new Fireviews at my former house. I'm looking at this used one for our new place. The stone is perfect as are all the castings. The cat assembling in this first generation Fireview needs replacing. They are asking $500 for it. I talked to Woodstock the replacement cat unit is $310 plus my labor which would make this like a model 201. Is this a good price or a high price? Looking for a nudge from one of you experts. Thx.
