I am well aware of that. I kept waiting for the market to be flooded with Tango 2s at “Going Out Of Business Prices” and thought/hoped I could pick up a couple (Main + 2 Fader Packs) for relatively cheap. But that didn’t happen, which sort of confirmed that it was a really good product and people were finding ways to make them work with any of the DAW updates. Last time I saw one for sale, it was close to $7K for a Tango 1(!!), which as you pointed out is E.O.L WITH ZERO SUPPORT, as the company has gone out of business. 
No way I was taking THAT gamble.
