SARB035 - where to buy?

I think I'm going to get a SARB035 and figured I'd ask if anyone has recommendations on where to buy it. I see them on Amazon, is that something I should be worried about? I apologize if this is a dumb question, I'm new to mechanical and auto watches. I've been re-watching YouTube reviews of this beautiful watch and I can't get it out of my mind. I have 2 Seiko 5's and have really enjoyed them. That cream colored dial, slender second hand, and even the cursive "Automatic" is really quite the combination.
