Hard Line Fittings..... Where to buy?

[abadsvt]

I was hoping to run all my air lines, fuel lines, brake lines and so on all in stainless steel tubing. I have been trying to find a good supplier for the fittings. I heard Swaglok was the fittings to use but I priced out 1 stainless fitting for $54. I am going to need a fair amount of fittings and was hoping to find something a little cheaper but still quality pieces. Any help would be great!
