Cypress is my main substrate. Newspapers come next if I run out of cypress, both are pretty easy to clean. I like the cypress more than aspen because the particles don't get as dusty.

I use both aspen and newspaper/paper towels for my snakes both in and out of racks: some like to burrow in the aspen but the paper towels are easier to clean.

Newspaper all the way. I'm yet to find someone to sell me unprinted newspaper. Oh well. Works great, easy to clean, doesn't cost much (if anything at all).
