found this today since I'm thinking of turning my CFC into and immersion chiller, should give ya all the info ya need . . .
BYW the $25 cost would be about $30 for me if I bought everything they listed
hose clamps - $1 each
25feet of 3/8 tubing - $20
25foot 1/2 garden hose - $7
tax 5.5% or something . . . they chage it too much around here to keep up with it
