If you've never ridden clipless, frogs are a great way to start. I say get them at that price. I've used a lot of different pedaling systems, and I think they are the most versatile. They're walkable, light, they have lots of float, they're easy to get in and out of, they're durable, and they take abuse well.

If you intend to race, I'd probably use something else, but they are great.
