Bionicle parts for own bionicle figure I need Bionicle parts to make my own Bionicle. 
Any good set recommendations? 
 Any LEGO set will do.  It does not have to be Bionicle.
There aren't many sets with big Bionicle part variety. I'm not sure what you are looking for. If you need specific parts I suggest to look for them on Bricklink. If you need to increase your Bionicle parts collection it might be better to look for local sales as Bionicle/Hero Factory are usually quite cheap.
