Looking at the $300 one in Kentwood?
The Pinnacle is your best bet. Millenniums aren't bright at all, Im betting the mini Pinnacle is brighter than a fullsize Millennium. The Pinnacle will be more reliable too. Millenniums are outdated 0.5w technology, and have a rather high failure rate: the boards inside corrode, the seals on the modules leak, modules dim and die, CID fails cause the light to half work... They are my favorite LED bar, I have 3 of them, but for primary warning, you wont want it. I only have one on a vehicle, its all amber for plowing snow. I don't run emergency calls or anything, so its bright enough for me. But I wouldn't expect traffic to move for it.
That said, Millenniums are awesome lightbars! Here is a link to My truck and Millennium:

Also, for what its worth, I have never paid more than $250 shipped for a Millennium - For $300+ you might as well get a used Whelen Liberty or Patriot, or the like. Good luck with the decision! :thumbsup:
