Buy tools as you use them.
Without knowing what you plan to do, its impossible to give you better advice.
I have "Sets" of Chisels" and "Sets" of Screwdrivers, where I have never had a need to use most of the pieces in the set. That was my mistake. Don't make the same one yourself.
What you need for basic timber framing will be much different from what you need to do joinery, and that's different from what you will need to be a cabinetmaker, or for carving gun stocks.
I can think of only a couple of molding planes, or scratch planes I might need if replicating certain schools of design for gunstocks on MLers, and I don't really need them UNLESS I want to do something like that. They, consequently, are NOT high on my "to-Buy" list.
