In five decades of being a passionate photographer, I always had to sell one camera if I wanted to "upgrade". As prices on these older cameras have fallen, I resolved to repurchase every great camera I ever owned in the exact model, color, and accessory set I originally owned. It took about 5 years, but I am more-or-less there. In the Medium Format department, I ended up with:
Hasselblad 501C/M
Mamiya C-220
Mamiya 645
Mamiya Universal w/G back
Fuji GA-645Zi
Fuji GW690II
2x3 "baby" Speed Graphic
Yashica-MAT 124G
And, very occasionally, a Zeiss Maxomar with an uncoated 10.5cm Zeiss Jena lens
Of these, I probably use the baby Speed the most because it packs light even with multiple lenses and backs.
For travel either one of the Fuji's or the Yashica wins.
The Mamiyas are kind of personal atavisms that I shoot now and then to remind myself of how I got here, lo these many years later.
The Hassy is for when I want to pursue the absolutely best possible image quality MF can provide, though it has also been a travel camera when mated with a 60mm Distagon.
Other than the Hassy, I didn't pay significant money for any of these ... well, the Fujis were on the pricey side. I bought old, servicable cameras and learned how to do basic repairs and rehab myself (which has its own rewards).
