The Zeiss 15x60 were the best at one time in big eyes. Even tho they are outdated and heavy, they still rival the current big eyes.
If you found a pair of 15x60 Zeiss at a fair price, I'd jump on them. For the price of the ones in the ad tho, I'd get the Swaro's.
I love my 15x56 Vortex Kaibab bins. I have been using them as much as possible since January and am very pleased with them so far. at $1200 they are hard to beat much like my 13x56 Minox at $800. However and a big however if I had to choose between the 15x60 Zeiss and 15x56 Vortex at the same price, I'd probably take the Zeiss. they are that good and they are proven and tested over years and years. Then again my Vortex have done great in the last 11 months.
Buddy if you can find Zeiss for around $1200 to $1500 in good condition, I'd be all over them. My buddy sold his about 3 or 4 years ago for a grand in good shape.
