Folding:
Kodak Brownie No. 2 (red bellows)
Kodak Junior Six-16

MF:
Mamiya 645 Pro-TL
Mamiya RZ67

I use the 645 99% of the time for both travel & vacation shots and the RZ67 for my "Serious" work. The No.2 Brownie comes out with me sometimes depending on where I'm going. The Junior Six-16 is still NIB, with all paperwork, and the original receipt. That I will never touch.
