I know this questions had been ask over and over again, but it's my turn now 
:)  I have a neighbor who purchased a silver puppy and is very satisfied with 
it...the ease of use, affordability; i.e. $99, and it makes great CS...but I 
noticed how small it was, that seems to me that it would take a while to make a 
gallon batch, correct?  If that is so, in my oh so inpatient American mind, I 
would consider buying a larger unit with the same ease of use, that by virtue 
of it's holding more water would make a larger batch of CS at one time. Can 
anyone recommend a unit that has all those qualifications?  I think you all for 
your input.
