Well i have a 4 year old beardie and he is on sandstone tiles with a sandpit in one corner as beardies do like to dig :smile: I think a lot depends on the age of your beardie too. Beardies under 6 months are better off just on kitchen roll, then move onto your preferred substrate. I am a huge advocate of sandstone tiles as they are easy to keep clean, cheap and they keep your beardies nails trim, thereby saving you from some nasty scratches :thumb: My boy only has a sandpit because he is a very accurate feeder so he doesn't take any sand with his food. He is also fed on his platform which is away from the sand, lessening the risk of impaction.
That's my opinion anyway, hope it helps :2thumb:
