Lens hood Flektogon 20/2.8?

[Anu]

So far I've used a screw-in lens hood with the Flektogon 20/2.8, but since this lens is somehwat prone to different kind of 'screw-ups' with the front element and the tightening ring, I was thinking if there are other kind of functional hoods for this lens? Any recommendations (ebay)?

Off topic: it seems like my never ending problems with the Flek may have ended, though I'm not holding my breath - it seems that I had screwed in the front element just a little bit too tight, causing some deteriation in the image quality. Flek 20/2.8 seems to be really sensitive regarding how it is assembled back into once piece.
