Main Halyard (non-Comptip) - 27' 3/16" Marlow Super Pre-stretch - $11.07

Outhaul / downhaul use the same line as the halyards (13' x 3/16")
Trapeze adjuster lines can use the same line as the halyards (3'6" x 3/16" x 4)
Tramp lacings - can use same line as halyards (15' + 15' + 19' x 3/16")
Buy 110 feet of the halyard line + the two different sizes of sheets + shock cords for the trapezes and you'll spend in the neighborhood of $100 on new lines.
All the lines listed above are polyester and quite UV resistant. They should last several years in the weather.
Do not kid yourself that the stuff at Home Depot or Lowes is suitable for this. Most of the stuff they sell is polypropylene - kinks badly and not UV resistant.
Prices above came from Annapolis Performance Sailing. They also have great deals in their "sale line" section.
