we had just the double slide one that the kids loved thankfully we found it used so got it fairly cheap
oldest boy and sisters oldest on it
Sorry only pic of it online I could find
Ours was just the slide kind if my kids had been younger when we got our I would have got the one with
the pool on the bottom.
If you can afford to get it and can keep barn cats/dogs from jumping on it I would suggest getting it as your kids are
fairly young so even at $550 it will last for years and kids will love it all summer long.
