Fafi for MAC - Scarf

I just hate it when I wait too late to get something when I know I should have bought it right then.  Tis the case with this scarf, from artist Fafi, part of her newly out, and naturally limited edition collection with MAC Cosmetics.  Ugh.  But, I can buy it on eBay for double the price.  Double ugh.  ;)  Should I go for it?
