Opinions/observations on HO rolling stock

[train_guy]

I suppose it would depend on the amount of detail your looking for vs what you can afford.I personally like Athearn genesis line(hoppers,Boxcars),or Atlas "master line"(tank cars).The most detail for the least amount of money.Intermountain,Tangent,Exact rail are definately more expensive,but still have alot of detail.If there be one thing about exact rail's models it would be their wheels,the flanges are huge(not very prototypical),but their trucks,side-frames are the most detailed,along with BMLA's trucks.I think it depends on your budjet more than anything else.If ya want to go "cheap" with little detail,then go with Athearn blue-box or Accurail,or even cheaper Model power and Bachman.
