I can't find where they're in business anymore. Have a look at this: https://www.trainorders.com/discussion/read.php?3,1236047 Looks like they where essentially part of Broadway limited a while back, but got spun off and apparently didn't make it on their own. If they're indeed using early 2000's BL tooling, I would pass on the PCM stuff. From what I've read, BL diesels haven't been good until very recently.
Thanks for the trainorders link. From that, they sound like pretty good models, other than maybe the sound system. And my layout is DC with no sound. The particular models I'm looking at do seem overpriced. Maybe I'll make the guy an offer he can't resist... Paul Moore
