I have a rule of thumb on swap cost effectiveness: use compressed ram first, if it's not enough, buy more ram. Because swapping is too slow to be generally usable. There might be a special case where being so slow is ok, but then cheap sata ssd in combination with compressed ram could be cost effective.
