>>4257580Mamiya 220 or 330 for 6x6. They are heavier than other tlr-s but bellows (close focus ability with built-in paralax correction), interchangable (very good quality) lenses and finders are imo worth it. Also they can take a beating.
Bronica ETR (ETRS if you want mirror lock-up, ETRC if you don't plan to use more than one back) for 645. They are realiable, light, have planty of good lenses avaiable and were produced and improved for a long time so you can easily tailor kit to your specific needs/budget.
I use both of them extensivly if that matters.
PSixes and (most) Kievs are notoriusly unrealiable - and prices now do not reflect that - that is all I can say abut them.
