Tone Commander sets really are the way to go, but I understand your position. I have a similarly-sized customer who insisted that I come up with a better solution. I found a refurbishing company that literally makes them good as new and their price is right. In some cases, I was amazed. Send me a PM if you are interested and I'll get you their contact information. You won't be disappointed.
