We have a set of knives, they've been great! They are pretty expensive in my opinion, glad we didn't pay for them. I've cut myself many times by touching one by accident in the bottom of the sink.

eta: I've seen some on Ebay, I was thinking about buying an extra paring knife and I think they were going for around $30-40 on there. If you're considering buying a set, maybe you could just buy one piece and see how you like it first.
