The A* 85mm f/1.4 original hood works but it's not any cheaper.
The irony of the first link in the post above is that it mentions the 55-300 which is 58mm not 67mm, but the product is 67mm per the details.
What I would do is measure the length from the shortest "valley" in the tulip, and the diameter. Then remove an additional amount equal to the thickness of the CPL filter you want to use and find a 67mm rubber or metal hood that is appropriate length or slightly shorter.
I have one single hood for both the 60-250 and the 50-135, so I use my A* 85 f/1.4 hood on the other a lot of the time.

Here's one I have asked for more details on (length) to determine if it might work for me as a spare/alternate solution.
