Is the online merchant Superkids Online - Nintendo Wii, Apple iPad 3G, Wii Fit , PS3, Nintendo DSi, Electric Scooters, Electric Bikes, Razor Scooters , Izip & Ezip Scooters , Xbox 360!? They have the best price on the kit (have had for over a year now)--$299.95 with free shipping. The other couple of merchants who offer it for $299.99 don't offer free shipping. I bought the kit last year and it's not light so if you have to pay for shipping, it won't be very cheap.

I will say that this kit offers the most bang for the buck. I love mine. Plus, you can always add LIFEPO4 after the fact. (This spring, I built my own LIFEPO4 pack that mounts into the Currie rear rack. The best news was that I got the Thundersky cells on sale for a total of $208 and built a 24V 20AH pack that's only slightly deeper and longer than the OEM SLA pack.)
