I think the issue is that the thread is titled "Lucky to have the vendors we have" not "Let's b!tch about these vendors." That's a whole other thread and feel free to start that discussion. If people wanna gush about these business, fine. Do I want to read any of it? Heck no. It's annoying and doesn't add much to the discourse. But now I feel the need to comment. Dangit.
Look, nobody's perfect. In this day and age people have gotten spoiled. I can't remember how many times I got screwed in the 80's buying custom VW parts mail order from California, living in Montana. Sometimes it was mistakes, sometimes it was criminal (literally). Nowadays with the internet and cheap express shipping, everyone wants things right this minute and if anything, any little thing, goes wrong, it's an unmitigated disaster and that vendor is the devil.
Mistakes happen but the vast majority of their customers seem to be happy (including me) which speaks volumes. I've read some negative stories over the years and frankly, not mentioning any names, I side with the vendor. People sometimes jump to conclusions or don't do their due diligence or they get impatient. But then these people, admittedly they are few, take every opportunity, and I'm not referring specifically to anyone in this thread, to bad mouth the vendor.
I've never had any problems with the vendors mentioned, even when things are backordered or a production run isn't finished yet and I have to wait an extra week or two. Boo. Hoo.
The only vendor I've had a problem with on this forum I never bought anything from and wasn't included in the original post that started this thread. But everyone else seems to love this dude so I won't rehash it (for the umpteenth time).

Jeez, that got long...
