Mwave offers the Logisys 15" Sound-Activated CCFL Light Kit in White, model no. CLK15WT, for $7.99 with free shipping. That's tied with our mention from last week and the lowest total price we could find by $2, although we saw it for a buck less last summer. It comes with one 15" cold cathode tube and a dual inverter.
From shoes to cookware, if you're willing to pay a little more for these awesome products, you may never have to shop for another again.
