Canoe cart recommendation

I was paddling in the Essex Chain this past week and saw many people with canoe carts. I've thought about buying/using them previously but have never made the plunge, until now. So I see this cart on Amazon for $20: http://ift.tt/1m6u6zV.



Reviews seem positive. What do people here use ? Any cart/carrier that is better for stacking boats than others ?



Thanks,

Bob
