HO freight car quality

[buzz]

AH now this can be quite a maze.
As I havs seen some cheap good stuff and some very expensive  junk
The price generally seems to depend on the type and level of detail
involved.
The main thing from my perspective is to make sure you have good
well aligned trucks and wheels and compatible couplings.
These will ensure good running other issues for the most part can be dealt with over time as knowledge and skills improve.
I have found nothing puts a dampener on things like a loco or car that just will not run properly and keeps falling off the track.
