I have a Cabelas brand "VXR" you'd think it was a Vexilar by their name, but it's actually a Marcum. It has the zoom and I have to say I like it for when the bluegill are right on the bottom. It shows about the bottom 25% on the zoom side and still shows the entire water column on the other side. I know a lot of people with Vexilars and like someone else said, I've never heard of a problem with one. If I buy another it will be a Vexilar. Haven't had a problem with mine, but the Vexilar seems like the top of the line.
