I'll grab the receipt and let you know, but to be honest, I didn't spend long shopping around for deals on each of the parts. I went to kent's. the copper was $1.59 a foot, so about $40. I got the heavy rubber heater hose that was $1.59 a foot as well...but could have gone with the $0.69 standard hose...but I wanted black and not see through green. The Tees were somewhere around $1.50 each, and the 2 feet of copper tubing was $6, when I only needed 1 foot. The end caps were about $0.50 each...all together with tax was about $110 taxes in. Like I said, I could have easily reduced that down to about $80 easy, and if I had have shopped for the copper spool, could have maybe made it for $65-$70.
I used a propane torch...which is the only way I know how to solder copper. I used lead free silver solder, but because beer doesn't touch a solder joint, you could use any type of solder.
If you don't have silver solder, flux, or a torch, I don't mind loaning you mine for a couple of weeks, not a problem.
Honestly, I think now that I did the job once, this could be done in under an hour for sure.
