There’s a lot to be said for the Kiev 60 (I have a 6x6 and a 6x4.5 Kiev-6C; almost identical, but also takes 220 film). These cameras are inexpensive but reasonably robust, and they take P6-mount lenses. I’m almost ready to get a K-88CM.
There's a lot of good CZ Jena glass out there, and the Arsat 30mm, 80mm, 120mm. 250/5.6 and 55mm Shift lenses (all 5, new/essentially new, for roughly $1100+S&H on eB) are quite good. A good CLA’ed K-60 with prism should cost perhaps $200, delivered. But for an additional $200 ($1500 total), I can, instead, get a heavily-used H-500 with 80mm lens (plus hood, etc.). Disclosure: I don't make money at photography; it is one of my hobbies.
There are also adapter rings that adapt K-88/Salyut-style lenses (old Hass-style) to P6 mount. Get the pack of 5, AND IMMEDIATELY SWAP the included locking rings on to all of your P6-mount camera bodies (the original one is slightly too small). This gives access to earlier glass and not P6 mount versions.
If you decide later that the Kievs are not the solution you like, the P6 lenses are still useable on many digital SLRs and 35mm film cameras. Just buy a P6-to-X Tilt Adapter or P6-to-X Shift Adapter (I have both, for my Pentax, roughly $200 total). Pictures of my Pentax with 55mm Shift + Tilt adapter may be seen on The Kiev Report.
There’s a lot to be said for view camera functionality in a 35mm form-factor, with multiple lenses, and not having hat to spend $1500 per lens to get it.
