I'd go with the Arrow. I have the TT and although it looks great I get tracking problems in the second half of the film (probably after the layer change). It may be a problem particular to my copy, but why take the chance? I don't have the (newer) Arrow, but I'd bet it's defect-free.
Thanks. I just made the purchase – including shipping it was under $18! Next time we meet we can lend each other our discs, so that I can listen to the second commentary (yeah right!) on the TT, and you can see the new bonus feature on Lancaster on the Arrow
