Thanks for the comments.
The Reef Specialty upgrade is no longer available, so I had to shop around to find one. I purchased mine from a local reefer who had decided to upgrade to the MRC Orca Pro 2.

I took down my Orca 250 right away and am getting it cleaned and prepped to go to another club member.
Here is the new (to me) Pro 250 after just being fired up and adjusted:
The Pro 250 skimmer stands 39.5" tall, an inch and a half taller than the MRC Oca Pro 2.
A view of the collection cup, which is 12" in diameter:
A head of foam after just a few minutes of operation:
And a parting view of the old workhorse with its heavy duty Baldor Reeflo pump... getting cleaned for its new home...
I'll report in a few days to advise how it's doing...
