Wanted: Replacement for Meade secondary. Sources?

Anyone know where I can find a replacement for Meade's secondary mirror and holder for their 16" dob Starfinder? I had put epoxy over the aluminum plate that the flat attaches to, and that wound up bending the aluminum piece when it hardened, which is distoring my images tremendously. I tried removing the epoxy (successful) and reattaching the mirror with silcone rubber, but this didn't fix the problem. I can't bend the aluminum back to perfect flatness, so I would like to either get a duplicate mirror and holder, or get something better to replace the 4" mirror/holder. Any suggestions? (since I did the epoxying, bright objects like Mars and Venus show as multiple ghosts, and I can't resolve stars to pin points at high mag, which is quite frustrating! I read in a post that someone thought the Meade 4" secondary was too big for this scope. Opinions appreciated. Thanks in advance.
