REMEMBER THOUGH - If you overwithdraw [take too much money] from the checking account, it'll automatically take it from your savings.
I have a checking account and a savings. So the money I see as available is anything in my checking account. That's what I really have to spend. But say I spend more than I have available in my checking account, the money will automatically be taken from my savings to cover that purchase so I won't have to pay any fees.
I would suggest going with something like that.
Or open a chequing account if you don't have one already and just use the money you put in that account.
