bed bath and beyond cup holder!
 

Found this the other day while browsing the store with my wife! It's super easy to remove too. Probably the best solution I've found yet. Speaking of cup holders, does anyone remember where I can get one of those cheap inserts to replace the OEM broken one?

ebay

at least that is where I got mine from. shipped from China. indistinguishable from the OEM ones (hell, for all I know they may actually be OEM ones). Not sure exactly what you are looking for, or what you consider "cheap"

I think you misunderstood what I was talking about. I remember a while back I saw on a website that they were selling just plastic inserts, something like a change tray that just fits into the pre-existing slot. To me, those crappy flip-up holders aren't worth fixing or replacing.
