Went to the Amherst Society Train Show in Springfield Mass over the weekend. Been needing another power supply and saw the MRC display. I picked up an MRC Tech 7 ampac 760 throttle. It has selectable momentum and brake features and a 20VA output. With momentum turned on if you hold the brake button down the train will slow down until you release it. When the brake is released the train will come back up to the throttle setting it was running on. I hooked it up temporarily on the railroad and ran a variety of engines large and small and the performance was excellent in both momentum and direct track input. If there is a negative it would be that the pack only has variable DC for track power and fixed 18.5 VAC for accessories. There is no fixed DC output terminals. If anyone is considering an upgrade from a basic DC power pack I'd recommend taking a look at the MRC Tech 7 series. It is also available as a dual throttle unit with the same features. MSRP is $99.98 but I found a dealer at the show who was selling them for $75.
