Oddball SSH port

[Michael Hipp]

Forgive if this is a stoopid question...

I'm starting to change a lot of my remote servers to have SSH listen on 
an oddball port. (A small bit of obfuscation that slows down the 
crackers ... whose population seems to be on an asymptote with infinity.)

Is there any discernible advantage to /which/ oddball port I choose? Is 
any one of the following, for example, any better than another?

     52, 502, 5002, or 50002

Just wondering if any part of the port numbering space is less of a 
target than another. Or if there are technical issues I'm not aware of.

Thanks,
Michael
