Need some help with bedding.

[Lokeenz]

So I just started setting up a terrarium for a ball python. I talked to a guy who breeds balls, and picked one of them out. He said a good cheap bedding to use is this shredded newspaper that you can get from TSC. I bought some, and then put it into the tank, but this stuff doesn't sit right with me.

It's really dusty, enough so that when I dumped it out of the bag and into a big container, I was sneezing for a couple minutes. I'm worried that this stuff will be harmful to the snake, as there are allot of small pieces. Is this stuff okay? Would I be better off getting aspen? I want whatever is best for the snake. And also, where could I order whatever I should get cheap, and preferably in bulk?

I've attacked a picture of the bedding.
