I am just about to move to the US from Canada. I have looked at all the major carriers and can't seem to find something that works for me.

I will use:

~ 200 minutes a month in total
~ 50 texts
~ voicemail, caller ID
~ about 100 minutes a month to Canada
~ will roam to Canada about twice a month

I basically don't use the phone that much. However, when I do use it, it will likely be on calls to Canada. I want something without a contract because I already have an unlocked phone that I want to keep. Pay as you go is fine too.

Does anyone know which carrier is the best for me?

Thanks!
