Barbara, the church stands are probably manhassets. Most orchestras etc use them. They make a model that "takes down". The table can be removed from the stand and the legs of the stand fold up, The whole thing goes in a nylon case. They are quite pricey ($65-$75 with case) but they are hard to beat. They will not fit in a day pack though. Thats the price you pay I guess.
Musicians Friend advertises a folding stand that folds up smaller; the table folds in half but I've never seen one so I can't really give a user report. They are cheaper than the manhasset but I don't remember by how much.
