White Noise Machine is wonderful!

I ended up with the SleepMate 980, ordered from Nature's Tapestry, who provided informative reviews on their site and great quick service.

The machine works perfectly and I've been sleeping really well. The only noise it doesn't block is the sound of my neighbor starting her SUV at 4 a.m. But no more dogs, no more noisy husbands coming to bed later than me. The sound is more organic than the digital files I was trying out. I don't wake up and feel cold and electronic.
