i am still doing a cost analysis, The entire unit will fit on a 48" x 26" work space. will be made mainly of High Density Plastic for ease of cleanup. The filling head will be removable for ease of cleaning after use. i started this thread to spur the interest in something i am the stage of prototyping and to see what would some interested parties be able to provide as far as ideas that could be incorporated into the design. So for those who need a number, looking at a cost of less than $2000. i want to keep it in the financial realm of home brewers and small micro brews who are coming up with their own homemade systems.
