Wire your own cfls...
Bare light sockets- $1.50
Take a $1 extension cord, cut the female plug off and strip the wires. The hot wire has writing on it and comes from the skinny plug. The hot wire connects to the brass screw on the socket.
Use a razor to expose as many connections as you want on your stripped extension cord. $1 cords are 6' so I had to use two for my build, but all 16 bulbs are drawing power from one cord 24/0 for about a year now with no problems. The cord isn't even warm.
I bought my bare sockets at Lowes, which has a section for people who like to make their own fruity lamps so whatever extra hardware you need can be found in one 4' section. (except the 90° brackets)
Double it up! get yourself some socket splitters ($2)
