Rule #1 always get bigger than you think you'll need, because you'll need it. If you are set on getting something really nice like your first link you can go to
http://www.danielmarshall.com/humidors.html and they have seconds onsale there for less than 50% of their regular price, these usually have a tiny smudge or imperfection and 9 times out of 10 it's nothing the average person will ever notice unless you are looking for it. They are beautiful boxes, I love mine, that being said, I filled it up in 20 seconds and was back to looking for something bigger.
