The Oil Rig drew me in as well. There were the only model that remotely fitted me at the time... Other models were too bland or too small. I still have it because I am too lazy to sell/trade (black with grey text... Black iridium). I moved on to Dispatch and the addiction has been on ever since.
My issue with the oil rig is that I could sell it, but it's been thrashed around so much that it isn't worth it to anyone to even have at this point. The hinges are loose, the lens is scratched, the frame is rough around the edges, but hell, i still wear it!
