If you’re not in a rush look for a used set of Swarovski 8x30 SLC
I’ve seen them sell used in the $400-600 range and they are way beyond what you’ll find new in that price range
He did say that $300 is the max, but I love this advice if you can stretch. Also, IF you can stretch, the 8x32 Cabelas Euro HD is sometimes sold used for $450, which is a great deal on really good glass.
