It's coming from Japan. I couldn't find any from the states, except the one on Amazon, for nearly $300. I will post back how long it took and the seller I purchased from.Sounds like a good plan.
You said you picked-up the BEC-113 on Ebay, did you find a local seller or is it coming from Japan? Unable to find any in the states.
If so, let me know how long it takes to receive and if you don't mind, the seller.
