I agree, Mad- Martha's punches are my favorite. I also like the way they look. I'm shallow, I guess. But they do always work.
I also love the EK Success punches. I love the way they lock closed/flat, too.
Whatever you do- never fall for one of those one dollar punches, no matter how much you think 'it's only a dollar and I need something that makes a little star or paw print or whatever.' They'll never work. lol
