Don't know, what are you targeting with the eggs? If you are curin some up for the upcoming springer run, most of the experts think that a "chem" cure is the way to go, for salmon. Try any of the store boughts such as pro cure, or try Amerman's. Ive heard good things of Amerman's but have never tried personally.
If you are targeting more steel, Id say keep it simple, such as the 3 2 1 borax cure (3 parts borax 2 parts salt 1 part sugar. If you want color add jello or use the pre-colored borax that pro cure makes. Ive used this cure the last two trips with success.
I would also suggest picking up the new egg cure book by Scott Haugen (sp?) . They have it at sportco and is worth the $10
