Clean, unglazed terra cotta tile is fine. If it is glazed or too smooth your geckos will slip all over it and it will stress them out or possibly cause them to have accidents or not get enough excercise.
Sometimes, you can use the back (unglazed) side of glazed terra tile- just put the rough side up.
Paper towls are cheap. I just bought 2 slate tiles for my 20 gallon tank, they were about $4 each- I bought the fancy ones but it was still under $10 the pair.
If cost is an issue right now paper towels are a cheap, safe substrate you can use indefinately, or till you can afford something more naturalistic that is safe.
