Hi guys, now that both the Kato and FVM SD70ACes have been out for awhile can anyone say how there's are doing so far? Personally I really like my FVMs. So how do you like your units so far? I want to get a Horsehead NS unit but I'm not sure if I should go with Kato or FVM. Could someone possibly put up a compassion of both? I know the FVM's windows are slightly off but I'm not to sure of how big of a deal it would be on a standard black unit. Thanks so much!
