As a user, I've never understood the attraction of the T model, because it feels like a step down from a Rolleiflex Automat. But sometimes logic doesn't drive the market.
By the way, you got a great deal in the swap. Any Rolleiflex will always be memorable. A DSLR is forgettable as soon as the next model is released. Most digital cameras depreciate faster than a new car that's been driven off of the dealer's lot.
