Karl - you should be more productive with your posts - why shouldn't he get that hopper, what are the advantages to using a Rotor etc. Your direct reply isn't very welcoming to any new players.
Smith,
It looks to me by your profile picture that you may already have gear sorted, I would personally say that saving up to buy a good second hand Rotor or Spire would be your best bet - you would lose next to nothing for the depretiation on any of those hoppers opposed to buying that Viewloader.
Either of the mentioned hoppers work fantastic and are reliable enough for you to just throw some batteries in and go, easy to clean and maintain, rugged and durable.
Hope this helps if you don't have a hopper sorted already.
