If you are trying to save money, just buy the winch with steel, then buy bulk syn line and a tube thimble. Use the hook from the steel cable and you are good to go with the lowest price. Will you have the best hook, no. Will you have a aluminum fairlead, no. But, it will work.
Redden Marine has the 3/8" amsteel for 2.11 per foot.

Just get 4' longer than you want the line off the winch. you will need 6"-9" tail on the winch drum and at least 24" will be the bury for the eye. Factor in the eye and little extra gives you the 4' more. But you could easily only go with an extra 3'.
But it will still run you around $180 - $190 factoring in shipping and tax if needed.
However, compare that to Viking's 3/8"x100 with excel hook: $373.
