Leave price out of the equation, then you can find the ultimate bag for your needs. A good down bag is going to last you probably 20 years of normal use. if the one you really want is $200 more, then you're talking about $10/year to have the best instead of something less. Per night it's going to be less than a buck. Think about it. I'd say it's better to wait a little longer so you can save up the extra dough than to get less than the best when it is something as important to the enjoyment of your trips as a good night's sleep.
