The M helps keep its secret meaning only for those in the trade or those who can't google.

I use FedEx all the time and have never had a single problem shipping or receiving. I am certainly no high volume user but probably average 15 packages a month.

I have lost 3 old time great Pentax's to OTS (old tired shutter) and can only say that I decided it happens unpredictably. Unfortunately for those, there was no repair. Sorry to hear the same problem exists in our digital age.

I have bought from Roberts in Indy since the early 70's at least and maybe before. Never disappointed and they are always helpful. Have done some repairs through them and was very satisfied. Glad to hear they are still around. I just threw out an oold Robert's catalog a week ago.
