Moving money?

[datgnat]

So we arrive on May 1st, and a question occurred to me. We're no doubt going to open a bank account with a local bank once we're settled, but in terms of moving money into the account, what are our options? We obviously don't want to have too much money sitting in the account at any one time, but getting money from our US banks to our Mexican bank? A wire transfer would be an ongoing expense--can I periodically write a check from my American bank to be deposited to my Mexican bank? Or is there some better way that I'm not imagining? I regularly move (small amounts of) money between a couple of American banks, butI imagine that won't work between nations...
