I paid $40 for all the decor you see in the pictures and an emperor 400 also two silver dollars i got free with the deal. I'm still trying to figure out how I want the decor.
Looks nice, I love the tree root in the middle. I think $40 is good price for it.
If you can, try to get a lighter sand. That will turn your trimac base color into nice yellow color, as opposed to darker, grey-greenish one.
