Been using a Report 8043 for about 3-4 years with 35mm rangefinders & slrs up to a wooden 4x5 field camera. I mostly use a Bogen 3437 3D quick release head, but with 4x5 I often mount straight to the tripod post since it has +/- 30 degrees of tilt. It dampens vibration very well. I really like the leg angle stops and how they work. It doesn't sink all the heat out of your hands in winter. Gets reasonably close to the ground for macro work even with the standard post in upright. The post is easily reversible, and I have a short center post as well for getting low. I rarely use my other tripods now, unless going to a 4x5 monorail.
Not sure without checking the website which model Shadow Images posted specs on, but there is a fairly wide range of models. Several places in the US carry them. HP Marketing distributes in the US IIRC.
