I just ordered my D'Focus Follow Focus v3 for my Canon 60D and now need to get some sort of rail base-plate to attach it. Jag 35 has a rail-less option for around $50 but they're out of stock. Can someone help me find a cost effective alternative rail system for my 60D. I want to get a rail system but I'm not sure which one I should use or where I can get one.
