I stopped in at our local farm supply store and bought these two fittings for a total of $5. They are solid bronze, and I plan to use them on our flag halyard. I priced the same (OK, similar) fittings in the West Marine catalog... Want to guess? $9.49. Each.
A lot of horse tackle is either stainless or bronze, and is priced without the "marine multiplier" - next time you are nearby, check out a farm supply store.
If it is springtime, there will even be real, honest to gosh peeps!
