BLI SW7 or Walthers SW1200

[FCIN]

Now that I'm thoroughly hooked on the DCC with sound, I'm looking at getting another sound equipped DCC switcher and would appreciate any input from any one that may own one of these. The new Walthers SW1200 got a very good write up in MR and it sounds like a great model. Some other folks have mentioned that the BLI NW2/SW7 models are good performers. Was also impressed with the MR review of the new Athearn EMD GP15-1 which could also be an option and would fit into my modeling time era too. Have seen some good prices on all three of these locos on the 'Net.

As I've said, I'd appreciate any input/thoughts/experiences any one has with any of these loco's, although it may be a bit soon for anyone to have purchased either the Walthers or Athearn locos.

Thanks!
