edge copiers

[rpilette@xxxxxxxx (rpilette)]

     I know this has been dealt with at one time or another by a number of 
     you folks.  We are looking at our edge copiers and thinking maybe 
     there is something better out there.  At the moment we are using a 
     machine made by Sharp.  What are other places using?  How do they 
     stand up to heavy public use?  Are they a true edge copier? In other 
     words how far into the margin do they copy and how far does the book 
     have to open?  I am asking about face down copiers for general public 
     use.
     
     Any insights, bits of info and opinions are welcome.
     
     Thanks
