    But then I think DIY....

    Choose your own LEDs.

    Decide on dimming. I'd suggest PWM, and probably resistorless etc. (IE - fix the maximum duty cycle to whatever %age - eg, maybe 10% to run 20mA LEDs at 150mA etc; maybe 3 (3-4V) LEDs in series staright from the LCDs 12V or 19V etc internal supply.)

    But I have seen really cheap PSUs, though I think they were for CFLs (with dimming).
