If financial circumstances force me to sell in the meantime (as it has in the past) I wouldn't cry about it. Wallowing in regret or whinging isn't a productive use of anyone's time.
Anyway, it's not the end of the world. Just buy yourself another when funds permit. Although I don't think you'll raise much money by selling a testicle. I don't expect there's much demand for used bollocks, although I must admit I haven't tested the market myself.
They come up for sale from time to time (Benellis, not bollocks). You might even end up with a better one - without that awful blue paint job .
