HunterDouglas Everwood… 149.00 Nice thick slat with a great standard valance. Cost more but worth it.
HunterDouglas Woodmate… 118.00 Slightly thinner slat and plainer valance.Great price point
HunterDouglas First Edition… 108.00 Thinner slat than Woodmate with a simple valance. Great price and you still get a Hunter Douglas product.
Graber Lake Forest… 85.00 Thin slat. Super plain valance. Less robust than HunterDouglas but still ok.
Anything priced below 85.00 for this size is a lesser quality product prone to binding ,warping and other problems.
