I don't know what a coleman perch is. Have you looked on Craigs list for a coleman crawdad? They are as light as you are going to get. I have one and I can load it and unload it in the back of my pick up by myself.They don't make them like this anymore. A good used one by itself should run you $200- $250. I found mine in Southern NH this spring. Thing was practically new and the guy was the original owner. Told me how he put it together in his garage. here is a pic of a crawdad
