My suggestion is a little different. If you are handy enough to strip and clean your doubles, you can learn to make your own springs. I've been making springs for twenty years to save money and downtime waiting for a 'smith. The spring stock is available from Brownell's. The only other things you need are patience, a few simple tools and a heat source. You may break a few at first but once you get the hang of it, it's remarkable how simple the process can be. Brownell's has instructions, or buy the Jack Rowe CD from Midway and watch him make a top lever spring. Some will say you need a fancy furnace or other stuff to harden and temper springs but you can do it fine by eye using the color of the steel. Jack Rowe doesn't use a furnace and neither do I.
