I wanted to purchase theiIn-wall ELV + dimmer (model # PD-5NE-XX), but I can't seem to find this model anywhere for sale. I've searched online retailers and local brick and mortar retailers but can't find it anywhere. Has anyone purchased this model and/or no where to get it. I'm interested in purchasing this one specifically because it has a favorite button built into the actual dimmer (instead of having to use a remote).
