I run several small duplicate games and was offering my players hand records and sorting the cards by hand. It took me about 3 hours per set of boards. I could not afford the larger duplicating machines, so was thrilled when I saw this affordable one available on Baron-Barclay in the US. I purchased one and the cards to go with it. However, since I run three or four different games a week, I needed more than one set of boards. The cards are expensive and replacing them is a definite expense. Also, I have good days and bad for the machine to work. Sometimes I have to pull the same board through three or four times. However, it still saves me time. When working well (either me or the machine -- am not sure who is causing the problem), I can do all 36 boards in a little over one hour. To summarize -- I like this frustrating little machine even though the cards are expensive and there are times I feel like throwing it against the wall. But wish I had access to one of the larger machines so that I did not have to experience the frustrations that come when that darn red light comes on repeatedly on the same board.
