They are selling this model but I do not know which shop. I know it's one of the shop in the basement. You have to go and check it out. Depends on what you are shooting. I would suggest a battery pack is quite necessary as usually hammerhead flash sucks battery plus the recycling time is far more superior if you use a battery pack. I think it comes with the bracket. Not sure with the cable. If you are thinking of using a quantum battery, the flash battery compartment need to be modified. My friend is using one but I am unable to contact him as he is in overseas and will not be back until June.
