I bought the $99 distiller too. By coincidence, this
wholesaler is located only a few miles from my home.
Neighbors and co-workers bought from this vendor
and are pleased. I intend to catch rainwater and
distill it, to avoid residues and/or volatiles from
hard, chlorinated municipal tapwater. The
result may be close to double-distilled water, at
less than the cost of single-distilled DW from 
retailers vending  products of uncertain quality.
