I have had one I've used for years... I likely should get rid of it and get a new one as the one Is not easy to set up with 2 people and dang near inpossible with one,,, and my other is not that much help.
However I"ve seen a lot of newer designs that look like they could darn near be set up one handed they are that easy.. Haven't seen a Coleman though (or rather, Haven't looked at it closely)
Best place to get Coleman stuff... Coleman surplus/closeout stores, either online (the obvious URL and click on the clearance store) or brick and mortar (Use the store locator or visit Burch Run, Michigan, Where I recently went shopping for coleman stuff)
