Personally i wouldn't spend that much money. I keep my geckos in tubs which are only $10 also I use a UTH. Ive kept my geckos on sand for years and never had any problem but I am very cautious about it. Ive also tried coco fiber which is pretty good just a little harder to clean(I spot clean it instead of using a scooper). I feed my geckos every few days live crickets and some times canned crickets.
