Basket setting for round diamond earrings?

I just "traded up" my pair of diamond earrings, and the pair I got are in a "basket setting". They have a lower profile, which is perfect for me because I wear them 24/7 (also b/c of the screw backs). Anyhow, they the tcw is .5 and I+, SI..originally $1899, but on sale for $737..plus my credit from upgrade. Was that a good deal? It seems too good to be true, and why isn't basket setting popular anymore? They sparkle so much, and it's nice that they don't poke out far. I'm just weary b/c the sales lady seemed a tad "snakey". So, any thoughts on basket setting?
