I know of a 150 for sale in the Prince Albert area. Good shape, was rebuilt by an acquaintance. A friend is looking at it also, but if he passes and you are interested, I will pass on the info. Kijiji is a good resource to try as well.
What does the damage look like on your bird? The negligible damage criteria is in the maintenance manual structures section. Depends how much you might want to "massage" things to keep your bird.
