Thanks again for your recommendation, OhhWatALoser. After doing quite a bit of research on many different humidifiers I decided to go ahead and order the one you suggested. It will supposedly cover up to 3200 square feet and only uses about 65 watts of power on high. I found a brand new one on Ebay for $125.99 (with free shipping). I could totally see those cheap little 1 gallon humidifiers not even touching the dryness in my house during the later winter months when humidity drops clear down as low as 16%, as i've seen it do.
For anyone else, who is looking for a higher performance humidifier here are the specs for this one:
