I'm totally biased since I just bought the BV ball purse in dark orange tonight. I LOVE the shape of the ball bag and chocolate brown would be very pretty... Don't know who you were going to buy it through, but Saks.com has a 10% off coupon going right now--"SHOPJAN" is the code. You'd have to miss out on their current free shipping coupon, but you'd save more with the 10% off.
I'm not so into LV and I think the Channel could look at little dated--but that's just my opinon. Spy's a little too trendy for me. You should think about what kind of purse you want. Do you want a:
1) trendy purse?
2) basic purse?
3) classic purse?
