In the meantime, my IIIf & FTbN can keep me company (you want heft? Find a nice FTbN sometime or an F1. Serious heft LOL )
The Canon FD system has to be one of the best deals going. The - very good - lenses are dirt cheap now; I recall paying $300 for a used 24/2.8, and even more for a 25-105/3.5. I saw a 24/2.8 listed for $30 not that long ago. And the zoom with a group of others for under $100. So you can build a very nice system very economically. Sure the lenses aren't useful on anything else but micro-four-thirds, but since you didn't pay that much, it's not a big deal.
Funny about Scott's comments about Nikon nomenclature confusion. When I was looking at (used) AF gear I found the EOS/Rebel naming a little confusing. Perhaps it was just how sellers were listing their gear, but the Nikon body-naming seemed more clear - even though the naming sequece doesn't appear to reflect the order in which they were introduced (e.g. my F65 I believe is newer than my F90). So I went with Nikon for my AF needs.
cheers!
