Check out Snipers Hide as mentioned. I have their 8-40 and like it. Their 4-20 is the best optically IMO. Overall I think it's still below a TT but above a S&B PMII. Their new line with the increased turret spacing would be what I look at if I was in the market right now. Great reticles as well.
I did have to send my brand new 8-40 back to be fixed. Process was easy but was frustrating to spend that money and have an issue out of the box. I would love to sell for a TT 7-35 but that TT price is crazy and I'm focused on hunting more than PRS the last few years.
