If you want a wider selection of larger punches, Google MSC Industrial, they have large selection (with some eye opening prices!) But in my humble opinion, the above noted Harbor Freight punch set will do everything you want it to do but at a much cheaper price.

I have both the Waldron sets and a set of hole punches (1/8 thru 3/4) that I originally bought to make bolt holes in gaskets when  overhauling aircraft engines (works very well on styrene too).  The set I still want but have been out of production for years was produced by Historex.  The punches were 6 sided and great for making styrene nuts and bolt heads. IIRC the went from 1/32"to 3/8". Still kick myself for not getting a set when they were available.

Harbor freight has a 25% off coupon for one day - April 5th.
