Last year when I was going to purchase a scope I could not make up my mind between the 10 power and the 3-12. Called up my favorite distributor and ask about the 10 power. He said Burris droped them from the line and he sold the last one that was in stock a week or so ago.
I got the 3-12 and it has worked great. I still might pick up a 10 power when I find one at the right price.
