I was wondering if any of you have any experiance with the kwickset ultramax line of locks. I have looked at these at the hardware store, and they "look" like they would be a decent challange. They are 6 pin locks with security pins. I have a couple of grade 2(

) kwicksets and a 5 pin schlage with spools.
I was just wondering if it would be a waste of money to get one of these to play with?
