After saying so many times on here that "A Crapra is a Crapra is a Crapra," I just bought one at Best Buy for my dad for his birthday. An XRS 9300.
Now, let me clear my name here--I would not have bought it for him if I didn't *know* that he has a fairly soft foot and only goes about 5 over (which makes a Crapra as good of a detector as he needs), and because I was able to get it for under half of the $100 retail price.
I'm going to look at another Best Buy later this week for the Whistler DE-1730 as a backup for myself. They were sold out at the one I work at.
