Couldn't agree more. Atlas and IM are the only one's that get me going each month. Though every time Kato does a stack car I get interested, Athearn does those awesome Ethanol tankers (and other than Atlas may be the only one's that might do a modern LPG tanker). I often wonder if I'll ever have enough IM Cylindrical hoppers.
MTL... they don't really make anything that I want to buy anymore. I used to get much of the CN and CP stuff, but now I pass on that as well.
