I'd send mine to Alactronics...in fact, I have sent several to Alactronics over the years, some for repair, many for modification. You can check them out at: http://www.alactronics.com/alacfram.htm or give them a call at 781-239-0000, talk to Scott Graft. I've found their work to be very impressive, and reasonably priced.
Thanks, Fletcher, I was leaning that way based on the response I received to my email. You're right about the price, and the description of the mods wasn't all hyped, so I figured they could substantiate.
