Thanks for everyone's reply! Lots of things to research and think about.
In the mean time, can anyone comment on the Yashica Electro? Seems like a cheap camera with a fast lens if you can get it in good condition.
I used the Yashica Electro 35 GSN cameras (pair) for about ten years before I went pro. I still used them in rare occasion after, but never for a wedding. Used them for reportage type shooting for school yearbooks. The biggest problem I had with them was the fact they were only aperture priority mode. on a positive note, the metering system was excellent. The lens is decent, but not spectacular. It also is not a quiet camera. Winding often is noisy with a clunk. The rangefinder is pretty good, though.
Hmm....AP only...I'm not sure how much I would like that.
Over the past couple of years I've dug my remaining beater camera out thinking that maybe I'll use it for something. It takes me a couple minutes to remember just how restrictive that auto exposure is. I'm much happier with my OM bodies.
I would actually recommend one of these Cosina/Voigtlander Bessa cameras. The new prices are reasonable and the resale prices are even more so and stable. I've been very tempted to pick one up and equip it with a really bright normal-wide like 35mm.
I never shot a wedding with my Crown Graphic. I was really tempted to, but...
The Olympus Chrome Sixes came with either a f3.5 or f2.8 lens. The last version (RII) had a rangefinder.
PS>> most times your going to use artificial light of some sort during the wedding so film speed should not be that much of a problem.
I quite enjoyed using the RB67 which I used with the left hand grip with a Vivitar 285 attached. As we were leaving the registry office, I particularly liked the look of disbelief on the face of the photographer with the next wedding party when he noticed what I was carrying!
