Heinrich,

I tried out the Arcbody and Flexbody; personally I hated the Flexbody, and I stopped using it after just one photograph. It felt cheap, and really didn't give enough rise to be worth it, in my opinion. I actually did like the Arcbody, but only because you could carry it and use the viewfinder to compose an image much easier than with a 4x5. But, definetely not worth the money and nowhere near as versatile as a 4x5.
