Screen House

Do any of you fine folks have the screen house that is available for the TM?  We looked at ordering one from Fiamma but they want over $600.  I told them I wanted a sreen room not an addition to my house.  We have ordered a set of the Rapid Poles and will make our own screen room.  I would like to talk to anyone that has one so I can pick your brain as to how the poles attach to the TM etc.

Thanks
Mike
