http://www.tf2outpost.com/trade/26003327 I went up to 50 people and asked them: If you had a choice do you prefer Kill-A-Watt or Terror-Watt? 35 Said Kill-A-Watt, 25 said Terror-Watt. On that, I find they should be priced around the same. There is a 10 key difference and I find that a bit unfair. They're both very similar and should be priced the same. If proof is needed on the kill-a-watt vs terror-watt I can do a poll next time.
