My opinion is that it should be allowed.  I have found and purchased rolls
which I never would have otherwise been able to locate thanks to members
posting ads.  Also,  I enjoy seeing the outrageous prices that some
"collectors" post their instruments at-  it affords me a hearty laugh and
endless hours of "did you see what ol' so-and-so is asking for that (insert
instrument here)?  Can you believe it?"  (a Reproduco for $35,000.00 is still
the subject of many a good dinner conversation).

Capitalistically yours,
