$700 seems way too high for that gear. I've had the older "heavy metal" 645 for years and have been quite satisfied with it. However, wanted to try the 645 Super for the different handling and body style. I first purchased a 645 Super body--no lens, back or viewfinder for $75 from a good seller on ebay (TMR Productions--they sell a lot of Mamiya equipment). It arrived in clean, perfectly functioning condition. I then went to KEH to purchase a back and prism finder both in bargain condition for a combined price of $80 plus shipping. The body already came with the crank winder but I really wanted the motor--although heavy, it made the camera much easier to work with. Back again to KEH, found a drive in bargain condition (functioned perfectly, cosmetically a 9+ except for the leather covering being a bit weak in spots) for $55. Altogether, the whole kit --body, prism meter finder and back plus drive for about $210. Remember, I wasn't buying any lenses since I had several from my older M645 body. I wouldn't recommend you follow my path if you're in a rush since the complete kit took about 3 months to complete, however as a frame of reference, you should be able to obtain an excellent 645 Super with 80 2.8 lens for well under $350. Also, regarding the motor drive vs hand crank, these are my observations. For waist level viewing, the hand crank is actually better and faster than the motor. That's how I use my older 645. With the eye level prism in place, it's just plain inconvenient with the hand crank. Good luck with your search.
