Yes thrift stores spell trouble for me as well this week alone I found 3 lights 2 10 gallon lights and one for a 20 long. I don't even have room for the 20 long yet maybe when I get rid of something else I will. I am helping friends with tanks so if I find a good buy I can always let them have it. Also found a heater for $1.21 but am going to give that to a friend who I am helping set up a 5 gallon planted tank. It was very hard to leave the other 2 20 gallon long lights there today both less than $10 a piece. Last week I passed up a great deal on a 30 gallon saltwater, I thought it was a 40 and that would have been to big for my friends place. I am passing on the addiction.
