Unless this is a troll post, the first thing you need to do is spend a few minutes doing some on-line research. Unless you are loaded-up with extras, there is no way 200 minutes should cost $60 on any of the major carriers.
Living in Burlington, you are limited to the big three and Wind (the other newcomers aren't covering your home area, yet) and Wind is only a reasonable option if you seldom use your phone outside Wind's "home zone" (see their map for details).
Amongst the big three, there is really very little difference between coverage and prices, but you need to do your own planning and reasearch before you go to a corporate store or dealer. How much do you use your phone and when (weekdays ro weekends/evenings), what options do you need, how much LD do you need, are most of your calls to the same few (five) numbers, etc, and of course, do you need voice or voice and data; a phone or a smart phone; can you take advantage of any bundling discounts? You can take this information and your questions to three dealers, or go to a place like BestBuy that sells service for all three carriers and is more likely to advise you on the best plan and options to keep your cost under control. It's my personal prejudice, but I'd steer clear of dealerships and go to corporate-owned stores who, IMO, know their products better and will be less inclined to let their commission scale influence their recommendation.
Maybe it shouldn't have to be this complicated, but it is and it takes a bit of work to get the best price and no one can help you without knowing how and when you will use the phone. There is no "best carrier" but there may be a preferred carrier for your needs once you have inidicated what those are.
