the thing that makes me worry is the "lower-end" and the "made in China" but, i could be wrong. they may be a great deal waiting for you. I mean, as long as it IS spanish cedar, and it does have a seal, how can you go wrong?
There are a lot of humidors made in China that are probably of good quality. I would think you would be okay as long as you are buying from a reputable dealer.
