The lid for the 9005,9010 and the 9015 are all the same.
I am very happy with Tunze Skimmers. I have moved from a 9005, to a 9010, and now have a ReefPack 500 with the 9010 upgrade (running the 9005 cup). I like a skimmer that is VERY quiet, and requires almost no intervention. I just empty/clean the cup every few days. Its "set it and forget it" type of skimmer. It just consistantly produces a quality skimate..........never stops.
I have had many skimmers over the years..........including some $$$ big name skimmers, and I am impressed by the Tunze DOC skimmers the most. They are almost silent in operation. They are reasonably priced as well.
They are a bit quirky...........but once you learn the ins an outs of the skimmer assembly, you are good to go.
Good luck............Herbie
