Is there a big quality difference between the different Xikar models. I have an Xi2 (the cheapest one) and it is ok, but I also have a Palio which I love. But because I am weird I guess, I feel the need to have more than one nice cutter. I wouldn't have a big issue with paying for a different model but wondered if I would basically get the same quality. If so, I'll just wait and get another Palio in a different finish.
