We used about 75-110 ton of it last year. Clearlane is the Cargill version of other trated salts. Its mag chloride and mollasses(sp). We have really good results with it, used less product and got better coverage. I would definately say its worth the extra money.
When this thread started I hadn't used Clearlane. Last winter I did and I wasn't impressed. Not sure how much liquid they are mixing per ton but there's enough that it runs out of a vee box within an hour of loading at the depot and pools in the bottom of a bin after a couple days. Wouldn't mind that but it appears there is very little material left on the salt after it sits a while. My gut feeling is that it doesn't stick(on the salt) nearly as well as Magic does and that it also isn't as effective as Magic.
