I'm pretty much the same, most of my cameras do have functioning light meters and you can still get batteries for them. (The Hi-Matic 7s takes a battery that isn't made anymore) or the Kiev 88 that you need to get a special finder for metering ability. I am however blessed to have two cameras that still meter but don't take batteries (The Rolleiflex and Trip 35), the first being a weapon of choice at a wedding, next to my Pentax 645, both meters are still dead accurate.
If I'm just shooting for fun outside, I'll just use Sunny-16 as a guideline.
