Anyone know where I can get a Hebrew 8.33?

You are correct, it is 120fps divided by the number of channels you are using. The GV-800's are not stackable, you could get 2 GV-2004's and stack them I have some brand new at a good price if you are interested.

GV-250 was discontinued years ago, it should not work with 8.2 properly. I bought one before from Esentia Systems.

Esentia Systems sells them , you have to call for pricing, they don't post it on the site.
