It depends on the car you are looking at. LBF made a very nice Trinity covered hopper, just as good as the Athearn Genesis version.
The rest of their line up is closer to Athearn BB then RTR. I have a bunch of their coal porters and some boxcars. All are nice models, but not highly detailed. The trucks are sometimes warped and may need replacing.
Hubert's now has all the LBF molds, and some of the cars are still available new through them. If Hubert's is still around, their web site was down last time I checked.
