"Here's a complete transfilling kit with the stand, Power Filler1, scale, hanger cap, and a 20lb. "mother" tank. Save time and money by refilling your own mini bottles. Get (12) complete 20oz. fills or (6) complete 2.5lb. bottle fills. That's around $1.50 per 20oz. bottle and around $3 per 2.5lb. bottle fill if your 20lb. tank fill cost was $18.00."
