Lens Hood for 50mm DR Summicron

["Robert Rose" <RJR@usip.com>]

Okay, after some time as a lurker I am taking the plung to ask a question,
which lens hood for the DR?:

I recently traded my Pentax 67 gear for:
     M2 with MR meter
    35mm Summicron ASPH
    50mm DR Summicron with eyes

The first results using T400CN confirm my hopes:  Even at 11x14 the
prints compare favorably to the 67, and at 8x10 the ASPH results are just
great, great, great.  :-)  My wife asks, "Nice lens dear, but does it take
color pictures?"  :-(

Now, here is my question:  The DR results are also great, but side by
side to the ASPH you can definitely see a difference in contrast.  (less) 
So, I think I must get a lens hood.

Which one?

B&H sells a rubber one around $25.
The rigid lens hood made for the new Elmar 50mm collapsible fits the DR,
and comes in chrome, and the lens cap from the DR fits over it, for $40. 
:-)
I could order an "original" DR hood from Deutschland, at over $125.
I could get the reversible black plastic one that fits the 50 Summicron,
around $70.

Any thoughts, or better yet, used ones for sale?

Thanks a lot, and IMHO as a lurker I have enjoyed this group.
