Nicole, I am shooting with Canon EOS 3 and EOS 500n.
But, if I had enough money, I would love to buy Leica, and especially Leica M6 or M7. Small, quiet, optics is great, and metering is enough for b/w negatives. And as you said you have handheld meter, it is not an issue.
I personally use older than me Konica Auto S2 rangefinder, and hope to collect money for Leica M...
Other rangefinders: Voightlaender Bessa R2, and if you have money Konica RF or Contax G1 or G2. Last two are automated rangefinders, Konica can use Leica M lenses, and Contax use Carz Zeiss...
Of course, if you are more for SLR and auto focus or autoexposure, then... I am shooting Canon, so I know only those cameras. Maybe something like EOS 30 or 33, Or even EOS 300 if money is issue?
If you are for SLR, but can live without autofocus, what about Contax Aria? Small (compared with EOS3), well built (as I heard), Carl Zeiss optics... In Germany it can be bought for 400 EURO... without lenses of course.
Olympus OM1, OM2, OM4... Zuiko lenses are great, I tried one
And good old Nikon F2 and something like that is seriously to think about...
OK, now I am of no help at all
