Great camera - go for it!
I just use silcon adhesive to fix a SVI push on adaptors to my Ds, can take both a filter and lens hood. It will pell right off so no damage to the camera.
Check the taking lens for dust, fungus etc., by setting shutter to "B" opening the back and looking through the lens. If it is clear, then fine, but some Yashicamats seem prone to "disintegrating lens coating" problems, which will almost certainly result in loss of contrast.
When you're shopping for hood, remember to pick one that fits the outside bay not the inside (filter) bay. If you buy anything other than the original Yashica metal hood it's worth checking. I bought a plastic one few years back that fits on the inside bay and I couldn't mount filters on so it's either filter or shade and those TLR's are useless without proper shade. I had to pay for an original yashica hood to have both the hood and a filter mounted on.
About two years back I snagged a metal Yashica shade off ePrey for about $16 -- it looked like it had traveled quite a lot, but was mechanically good and I touched up the paint chips a bit.
I just use Rollei Bay I accessories with my 124G - hood, filters, and Rolleinars.
I'm not a chemist (that's PE's department), but I don't believe battery chemistry is "killed" by cold temperatures. Reactions are just slowed way down. At least no problems with these cells so far...
Good to know...
