Dan,
I am curious, why do you fancy this marine radio? A post on that review thread made in 2012 said if you can get one for less than $900 you are doing good. The only one I find online is this one – Ray 152E MF-HF SSB Radiotelephone – and it is out of Germany. I set up an eBay search and if another shows up I will let you know. A ten minute search online didn’t yield any other results for me. I am going to try and make contact with the folks posting to the review and tell them you are in the market. Maybe one of them will have an idea.
Good luck,
Phillip
