@abd1 I just came across your OP thread that provides much more detail. Feel free to PM me to continue the discussion off thread. I've used the strikethrough function, for my earlier post.
I cannot help you with your question since I did not compare the two models.
My feedback, therefore, is general.
I’ve learned it is far better to stretch one’s budget and get what will serve you over the longer term.
If I was in your position, I’d choose the original Terminator with the latest board OR wait for a used Terminator II listing.
All the best in your choice, whatever that ends up being.
