I wholeheartedly agree with Steve. I have a bit of a quiver of crampons now, but I have almost exclusively climbed on monopoint crampons since since I began climbing ice. There were Charlet Moser, Grivel, BD and now Petzl crampons in the mix and they have all had their positives and very few negatives. Modern climbing gear is incredible. So the trick becomes getting really familiar with a tool you trust.
