what i would do to save cost and still have it be a diy job. is to get a rigger ( mail order ) to make up all the cables with pressed fittings on the top, and have the cables a little long. then cut and use stayloc or what ever on the bottom end. this makes sense because you will save a little money on not using the mechanical fittings for the whole thing. but it is still a diy job, and some parts are reusable. also having a mechanical fitting where you cant check them easily is a bad idea in my mind.
this is what i did when i needed a new stay, cost for a 38 foot stay with a pressed top and the stayloc fitting was about 80 bucks ( cable size .220 ) at that price my whole boat would be less than 700 ( 8 total stays/shrouds 36' mast length )
