I'm in for one.... got it from Amazon... there is a coupon for $100 off. Ordered on Thursday, received today (Monday).
Total cost = $1306.79 (Battery - Coupon + Tax + "Free Shipping")
Arrived from Fedex in a plywood box... inside was another well packed cardboard box.
Took it apart to check for loose wires. One of the negative sets of 2x 7 gauge wires was a bit loose. 1/8 of the turn to tighten otherwise everything else was tight.
Going to fully test it this weekend. (capacity, balancing, etc)
If all goes well, I'll be getting a 2nd one. If I was buying 3-4+ I might go with something else since freight costs start to pencil out.
