Celestion SL 700 surround replacement

Has anyone had Celestion SL 700 woofer surrounds replaced? The originals are cracking and I really miss listening to them! I have given up on finding new replacements, and want to find a repair shop that will get them to sound as close to original as possible. Recommendations would be greatly appreciated!

I've bought a goodly number of parts from this guy(Bill), since closing my own speaker repair business. Very knowledgeable and pleasant to work with: (http://millersound.net/service.htm)
