I hate to say this, but I get Casey's point. If you've owned a bag/stool combo and a Simian they're not even in the same ballpark. I disagree on the cost though. I bought a squirrel monkey several years ago, and it's the bag (of 8) I use most when I don't bring the cart. It cost as much as Casey's setup but still looks like new. That made me buy a heavily-used Simian for $100. I loved it for a few months before deciding to keep the Ergo, sold it to a friend for what I paid for it, and he's still using it. It still looks like it's in the same condition as when he bought it. I believe the Gorilla Boy Simian is worth every penny.
