As someone who literally just spent $20 on one I found on Amazon, I think I can say that this is overpriced. As long as there are no cracks or imperfections then it's simply another marble m&p.
turnKeyHow is yours working out for you? If it is handling well, could you please tell me the make and model? I would like to have a m&p for small amounts of berries that will be mixed in to drinks.
