I found a great toy today! It seems like I played with one of these as a kid, but never realized it was actually made for kids. I found these at the local grocery store for a dollar a piece. I love the 'play-ability' to cost ratio! I gave my nieces and nephews several of them and they played with them for hours... turning them into marble runs, telephone lines, whistle wind mills, and more! The only downfall of this toy that I can see is that they come with a barcode sticker attached to one end... while removing it leaves behind that awful sticky junk.
