IMHO - A person gets what they pay for. However, a recent issue of Chef's gave the the Forchner commercial/black handle knives a great review & they are pretty cheap! I bought some and agree. They are easy to sharpen and maintain an edge really well.
The Wustof or Henkel breands always work well. There are a million out there - just get a comfortable angle & handle.
