As some of you know, I will be going to New York City after Christmas this year. I'm going to buy a card based MT such as a swisscard for parts of the trip where anything else may be frowned upon. I am wondering if anyone has had good or bad experiences with specific models and/or if they prefer one over the other and why. Also, if there are some less known models that might be better than the swisscard I'm open to that as well!! Thanks everyone!
