ok i have a different take. sometimes there are periods where you luck out and the bags you want are on ebay. if you do not have to worry about how to pay off the extra sophia, you should go for it.
I have controlled myself when multiple bags i wanted appeared on ebay thinking i could buy it next time. but the thing with out of production bags is that there are only so many and it may be awhile before it shows up again and it might not be in great condition.
So my take is this, if you really love the bag, go for it if purchasing it doesn't require you to not eat for a week. if you only like it alot but don't love it (ie it's not your must acquire list) then wait for your 2 new beautiful bags to come. that sage sophia you have is to die for. i love the color!!!
