1: DSLR RIG SJ-5 Set is quite simple rig, but has everything to get you started including Gini's new i-Focus Follow Focus, which I ordered last week too.
2: DSLR RIG EXTREME-1700 is full blown rig, with loads of extra bits, including a top handle, magic arm, cage like brackets. Of course it also comes with the ifocus. At $299/£185 it is a great value for money. Just about 3 months ago I paid £300 for a similar Gini rig on it's own.
