That is nice...it looks like the difference is the 6 LEDs along the bottom. There are some guys on the Optima Forum who know how to "melt" open the housings and install additional LEDs, etc. Or there are even pretty cool people on this forum (WILL @ Karbon Koncepts) who have connections and may be able to locate the items at a reasonable price. A reasonable price, however, may still be over a grand apiece with our luck.
They do look cool,though. It's just a matter of availability and cost.
