LT, I have the 20 - 60 x 80 Skyline ED angled. I love it. It is a great scope. if you are looking to get the the straight, I think Doug at cameralandny.com has them for around $450.00. I payed that for mine used. The glass is clear and sharp. I have a buddy that has a Swarovski 20 - 60 x 80 HD and while there is a difference, it is very slight. Not worth $2500.00. I was shocked and he was dismayed when we set them side by side one evening scouting for Muleys. If you have the extra coin, the new Voretex Viper that is replacing the Skyline will be an even better bang for your buck. Stores around here could barely keep the Skylines in. I'll bet the Vipers with HD glass will be harder to find. Would, I buy the Skyline again? Without Hesitation.
If you have any questions, PM me and I will be happy to answer them for you.
