I have the Lee Valley chisels and they work fine. They keep an edge pretty well. I also have the Lie-Nielsen's and they are very nice. I tend to use them only for the "good stuff." They handle well, too.
For really high end, try Barr chisels.
The Veritas Detail chisels (sold at Lee Valley) are also nice. They have one at 1/16'th, a useful size. I've found anything from Lee Valley with the word "Vertitas" on it is very high quality. A set of 5 is $135. See them here:
