I haven't picked up a copy of DX yet, on the back burner for me since DS and Party keep my Tetris fix satisfied.
Local mom and pop game store/arcade has Grandmaster 3 on rotation. A local fan (of the store and Tetris) purchased the PCB himself so he could play it on an arcade cab (candy cab).
I like Tetris Collection on the PS2:
It has some good options for resolution and scan lines so you can get the perfect "feel". From what I gather, it's three Sega arcade ports.
