Yep, I figured the tanks would be more reasonable as well. I called Middlesex Welding on Rt. 1 S in the North Brunswick area and the prices were $80-140 for a 5-10 lb tank, plus the cost to fill it. I am going to call them back and see if they will fill tanks bought elsewhere. It would be really ood if I could fill there because they are just around the corner for me.
