I bought the photoclam multiflex, which is the korean copycat version of the cube, when the cube was still around 2500€. I paid around 900€ shipped to Germany then.
I must say I have a constant bad feeling about supporting theft of design, meanwhile I tried the Original a couple of times, but I prefer the photoclam. It gave me 5 years of great service, some things are even improved upon the arca cube:
- the Arca cube's clamp sucks. it's fiddly and hard to open
- the finish makes it look always greasy
- the knobs are easier to turn on the multiclam as they provide stick on larger ones. the Arca's knobs are small and stiff
- I certainly don't have the need for an expensive leather case, at the time it only came as a set
- it is much easier to communicate with photoclam than with arca swiss. My emails got never answered and don't get me started on the webpage!
I had on internal bit broken on the multiflex when I dropped the tripod on the head. Photoclam replaced it for free, the head was sent to Korea and back to Germany within 4 days.
Just recently I bought the d4 to go with a gitzo serie3 systematic as a lightweight option. I actually ordered it directly from arca swiss at Photokina 2010, promised to be delivered 6 weeks later, but staying in contact with them was not possible, noe emails or calls were returned. I bought it from a dutch dealer 4 months ago.
it is a fantastic head, it is confusing to use besides the cube/multiflex, as the knob configuration to turned by 90°.
Open the kobs, grab onto your camera and move it to where you want, close the gearing knobs and fine adjust, just beautifull. now I see no reason to us a ballhead anymore. I even used it as a video head once, as you can only lock one axis and keep the other free.
Again the QR clamp sucks, replace it with a RRS one.
The manfrotto geared heads, about alright, but compared to the d4/cube/multiflex much less precise. and the stupid manfrotto quick releas system feels very outdated. I had a RRS clamp on top of the quick release, didn't help stability.
