Standard rig is, CP950, FC-E8, Bogen/Manfrotto leveler & rotator with old Ipix CP950 mount on top.
I have the complete Bogen/Manfrotto QTVR 302 PLUS unit but it is totally useless for FE spherical images. The two sliding arms used to adjust the nodal point are virtually impossible to edit out in the finished pano. Aircraft carrier is a good description, Point.
Having said that, if you wanted to mount a heavy 35mm camera lens combo to shoot none spherical panos, this unit is the weapon of choice. It is solid, offers a wide range of nodal point adjustment, is built to last, and is bloody..............heavy! So you will need a good tripod and also a Sherpa to lug it around!
Thomas you seem to be happy with your 312. I am not familiar with this one. Does it include the nodal point adjust sliding plates? Or is a different design to the 302 Plus?
Also I am not sure that there is anything to be gained by upgrading to a CP5000 for web work. The CP 5000 for print work would be a great asset. I plan to wait for the D100 to use for print work.
