Re: Cheap boat parts?
Know the Chinese word for quality?
They don't have one.
For rope, try Milwawkee Rigging on ebay. They deal in New England Rope and are always auctioning pre-cut halyards and other useful lengths, often with a splice on one end, and they tend to go very inexpensively if you don't need something quickly and can wait a few weeks till the size, length and color you need comes up. Lots of sta-set and sta-set X.
I always check with them first. I have no connection with them, just a cheap parts hound like yourself.
