For more than 30 years I made my own wood carving chisels. They worked great and I still have a lot of them. Since then I have probably bought a thousand dollars worth of the best tools.
My advise is whatever you buy get the best grade or else learn to make your own. Cheap stuff isn't worth owning and will discourage you. To do the best carving you need very good wood and very good tools in my opinion. It isn't hard at all to learn how to make a chisel or even a gouge. There are probably dozens of makers on this forum who make their tools.
