One and a half stock trays from Cheap Humidors. Used poplar strips at the bottom for the slides. Fits great and at around $15 each, that's a bargain! A few hours work and bingo, 5 custom slide-out trays in my little old 20 bottle vinador!
Agree on the power out thing...same with mine. I also set on highest setting - 66. Need pix of yours when you're finished to see how much room you have to fill!
