Advice for a Limey

I’m after a set of Polaris mirrors for my RZR, Part Number 2879528. I’m being quoted silly prices here in the UK.
I’ve looked at the vendor list and to be honest I’m bewildered. So many to choose from.
So which vendor would you buy from? They would also need shipping to the UK.

If any vendor wants to quote me a price I’m happy to call you up and pay over the phone today for them
