For the same price as the Tachihara, the Shen-Hao gives more movements and a Graflok back, but in a heavier camera. I think either is a very good buy.
I went with the Shen-Hao, as the weight didn't bother me and I figured the extra movements might come in handy. I've used the Graflok back a lot (for roll film holders and a Grafmatic), but the extra movements have seen very little use. Still, I think it's the right camera for me. For others, the Tachihara is a great camera. I don't think you can really go wrong with either.
I love the look and feel of the Ebonys, but could not justify another US$1000 for a camera with basically the same level of utility. Again, the decision was the right one for me, and might be wrong for others.
