I like the no-name Cashmere scarves. I own a Sak's brand Cashmere, and a brand I don't recognize that I bought off the B/S forums here. Both were $50 each. Great deal, and feels just like any other cashmere scarf. I suggest you scour the forums here... tons of great deals.
I wouldn't buy Burberry. You are paying for the brand and everybody and their mom owns one. its too played out at this point. If you must, go with the dark grey/charcoal check Burberry pattern.
