Ordered a Shorai battery off of Amazon's The Outlet on 05/21/2013 and received it 05/28/2013 (through Memorial Day weekend). I ordered a LFX21A6-BS12 for $179.12, no tax & no shipping. Good price & fast shipping. Battery feels like a plastic toy compared to the original. Dimensionally the Shorai 21A is only slightly smaller than the 14A original. I used one 5mm and one 10mm piece of the supplied foam for the bottom of the battery tray to make the retaining strap tight (probably not needed). So, good provider and so far a good product.
