...This exact model is no longer available, but I ordered a very similar replacement, since I've been happy with this method for controlling humidity in the slip. I had rigged a flexible tube to dump the humidity down the drain, and I'll do the same for the new one.
Now that the season is waning, I thought I would post an update.

First, I'm happy to say that the exact model that I purchased three years ago is once again available for web order from Home Depot. At about $49, it's a good low-cost option.

Last April, when that unit crapped out, it was not available so I had to do with this other model from Amazon:
Amazon.com: Sunpentown SD-652 86-Watt Mini Dehumidifier: Home & Kitchen Amazon.com: Sunpentown SD-652 86-Watt Mini Dehumidifier: Home & Kitchen



The new unit has the same power brick as the old one, but has a larger aluminum fin for heat transfer, and appears to remove humidity a little faster than the previous one. Its large 2-liter tank typically fills in a week. I've attached a hose to it to drain into the sink, so it keeps going even if I don't make it to the boat for a week. Humidity in the cabin is typically 40-55%, and even on the most humid days it has never gone above 60%. (I have an electronic humidity sensor with memory, so I check frequently.)

In addition to the dehumidifier, I have two electric clip-on fans that keep the air circulating in the cabin, which I'm sure helps the efficiency of moisture removal. One blows forward toward the V-berth, and one blow back into the aft berth. The latter one also blows across the power brick, which really helps keep it cool since the dehumidifier draws a lot of watts for such a small device.

Overall I'm still very pleased with this arrangement, and for people who have shore power available I think it's a viable alternative to the Nicro solar vents. Those with larger or wetter boats might need two or more of the dehumidifiers to keep up with the moisture.
