If you are referring to the one that I think you are (it is about $90 on ebay), they don't seem to be worth it from the video I watched. You need to hand feed the machines, pretty much one at a time to prevent jams. Then if it does jam, you need to take the time to fix it. I would assume you would save very little time, if any.
Now, if you are talking about the one with the hopper, that you just dump a few hundred at a time, and it feeds it one at a time, then I would think that would be worth it. However, that one is 4x more.
