How strange, I was researching SAD earlier today. Synchronicity!
I also have the Apollo GoLite. I got it at Costco for like $150 a year or two back. It uses bright blue LEDs.
It is quite small and light-weight and bright. After purchasing the unit, I realized there was an upgraded model for a few bucks more that has an alarm setting that makes it turn on at a certain time. This is a feature you will definitely want.
I need this because my circadian rhythm is messed up, and I am a natural night owl. So, they recommended I use it an hour before I need to wake up each day, and stare at it for 30 minutes.
After trying it for a few days, I came to the conclusion that if I am already up an hour before to use it, I can just drag my ass to work! What is the point! I also read that blue light can be dangerous to the eye, even though the GoLite says it is safer than normal light boxes.
Even if you decide against the GoLite, take the test here, to see what schedule you should use a light for SAD:

It is free, and will tell you when to use your light to adjust your moods and for what length of time. I assume it will be similar no matter what light box you use.
Anyway, I have now decided that I want to have a dawn simulator to wake up to and see how that works out. There are lots of cheesy and expensive models, most over $100. I found a cheap solution just today that I am going to try:
Sunrise simulator (dawn simulator) supplements your alarm clock. An inexpensive (cheap) treatment for SAD, shift work, winter blues, jet lag, or morning lethargy. An alternative to light boxes for under $25.
Basically, you plug a bedside lamp into it and plug it in 8 hours before you want it to start getting light, and it ramps up the brightness. I will pair it with a cheapy $5 timer from Home Depot to turn it on at the right time 8 hours in advance, problem solved for $35.
One last thing that I just read, that might defray the costs:
About 70% of insurance companies will cover the light. You may want to contact them before your purchase to see if they will cover it. You will also want to get a prescription from your doctor. Insurance info:

Good luck on whatever you decide!
