Well, I ended up bidding but losing out on the magenta - it went for around $320! But I did win the yellow! I am v. happy with it b/c I got it for a bargain at $203. AND I'm thinking of bidding on a magenta Stella if it comes up on ebay and I don't like to have matching bags and wallets. Thanks for all your input everyone!
p.s. I used auction sniper for the first time - it's GREAT! Does anyone else use them?
