I just recently switched from news paper to substrate and i am a much happier keeper. i used newspaper for a long time because it was free and it WAS easy. But i one day cleaning i realized i am changing the entire substrate in every tub EVERY time their dirtied. Same thing with paper towels which i liked better because it looked cleaner but had i had the same hard time justifying it as i did with the newspaper. I have been using Repti-Bark for the past month and i love it. I got a smaller scoop and spot clean, now cleaning takes me a third of the time. I don't know why i haven't been using substrate the whole time. i was going through ridiculous amounts of newspaper which also created a ridiculous amount of garbage. Its cheap, i buy in bulk but i just saw it at Petco for like 10 bucks for 10 Quart bag. And because your spot cleaning you don't have to change it as often just add a scoop or two when your spot clean i go through about 50 quarts every couple months. So my vote definetly goes to substrate and peculiarly Repti-Bark it holds humidity very well and looks really nice, clean.
