Would you, interested in wine wine-related products, buy a $300 device? If your immediate inclination is to answer no, consider this: Your collection of wine paraphernalia may already include the basic butterfly corkscrew, or maybe you've upgraded to the Rabbit, the elegant, easy to use opener that costs around $60. You probably have a decanter as well, because you'll occasionally have a wine that needs it. Finally, to store a small collection, you may consider investing in a wine cooler, lest your subzero become overloaded with bottles and your weekly haul from the farmer's market. And to amass all of that is about $300, minimum.
