Well, having been sole breadwinner earning $6700 the year Dad was out of work (he was raiding his retirement savings to cover the mortgage and I had the best job I could find), I'd say anything more than $550 a month is good for me! And hey, I'm doing not quite four times that now, so I'm pretty happy with life.
Of course, if my boss up and decides to give me a raise, I certainly wouldn't say no to a few hundred more a month.
