I don't know if this is a kit you can purchase at a store or one this guy builds.....it seems to come with the sink hookup also, which usually runs about 30.00 alone!
It would fit my bill for now, I am working on the kitchen in the basement, and for now a portable would be great, but this would allow me to get and undercounter model, use it for now, and when the time comes, install it permanently...
