I have heard good things about Avon Celli regarding Polo shirts.
I do not buy into the whole "high end" Polo thing though (I have yet to find a big difference between a polo from a lower tier brand like Lacoste and a higher tier brand like Cucinelli or Loro Piana). I have found my Lacoste Polo's lasting fine, usually 2/3 years. I cannot see you getting much more mileage from a higher tier brand.
Unless you are going for one off designs, most solid colors or basic horizontal stripe / plaid patterns are available season after season for any particular brand.
I see little point in spending more than 100bucks on a Polo unless you find one with an unusual pattern that you must have whatever the cost.

It wouldn't look inappropriate on a polo though, I don't think, because there are only 2-3 buttons and they're often thicker plastic anyway.
I love MOP buttons but most people wear their Polos with all buttons undone or at the very least the top one / two button(s) undone. Correct me if I am wrong, is a Polo nothing else other than a tee shirt with a collar? If so, I am surprised people are looking for high end features on what is a very casual garment.
