This build currently uses 205 pieces of (mostly) Lime Green bricks. Using the approximate price per brick of $0.15 puts this kit around $30. There were many compromises in this build to get it to the model stage and I estimate that given the full catalogue of Lego parts in Lime Green, the part count of the final build could be reduced by 25%.
If you would like an Android of your own then please support this project. If you want to build one of your own there are a couple of limitations you should be aware of.
A) Some of the Lime Green parts used in this build are not commonly available.
B) Quite a few of the parts are expensive.
Generally speaking, the reason for B is because of A. ;) If we can get this built as a kit, then you won't have to worry about A or B. :)
