5x5 is not much space to work with. Where are you going to store those 50 CTU's if someone ships them to you?
Any machinery is going to have a footprint that is going to make it a little tight for you. I could find room for one of those RollCrackers if I could just get Santa to bring me one.
Since you will be be liberating the pennies the old fashioned way I have a couple of options. You can use the whacking method or the peeling method. I have a 1/4" steel workbench next to the desk in my penny processing center. I just crack the rolls like eggs on the side of it. I can open rolls that way fast enough to feed 2 Ryedales simultaneously, but that is going at a pretty good clip.
When I want to do it a little slower I just take a few of my 2.5 gallon buckets into the family room and shell 2 or 3 boxes into each one using the peeling method (fingernail or small knife) if they are machine wrapped rolls or open and dump if CWR while watching TV. Then I just take the buckets out to the penny processing center and run them through the Ryedales.
For Brinks wraps you just bend the rolls and slide the coins out. There was a thread long ago about being able to shoot the coins out of the plastic wraps with a compressor, but I have never tried that.

If your percentages are low.. just sort more. If your percentages are high.. just sort more
