I have been wanting to try making this photo cube puzzle ever since I saw a kit on sale about 10 years ago. I had that instinctive reaction, "I can make that, I don't need a kit." Perhaps I wouldn't have waited 10 years if I had not had that thought. Last winter, I finally went to Hobby Lobby and JoAnn's and bought everything I thought I needed.
The key for me was that I bought a Fiskars square hole punch (at JoAnn's), then went over to the wood aisle at Hobby Lobby, and found wood the same size as the punch. This made cutting out the pictures easy, fast, and neat. You can just stick to a paper cutter if you want to save a few bucks. Remember, craft stores usually have 40% off coupons so just print one off before you head over, and you won't spent much on the tools, like the hole punch.
