I also have the Waldron punch set, and I feel the skinny plexi top is very fragile. I think that's why I have seen so many broken sets. The Armour Extra round and hex sets are more robust, but the metal rusts like crazy. Still, they are providing years of good service. Strangely, they don't give any indication of the sizes of the punches, unlike the Waldron set.
The beading tool on the left is not a punch tool per se, but rather it makes little domed rivets using a big stinky rubber pad for a backing. The set goes down to crazy small sizes, like 1/48 scale buttons for people! I have not had a chance to use the smallest size, but the larger ones have been used on 1/35 armor kits. BTW, I have seen the beading tool for sale at a vendor's table at one of the IPMS Nationals, and it was considerably cheaper than the 8,800 Yen I paid. The set didn't come with the stinky rubber pad, but I doubt that it would have added $40-$50 to the price tag. I think it was at Radu's booth, but not 100% sure. A friend picked up a set.
The giant rubber mallet is what I use for the punch sets, It might sem like overkill, but the weight combined with a gentle touch is all that is needed to knock out the bits and pieces.
It is also great for whacking my head whenever I make stupid mistakes!
