Where do you go for advice on excavator attachments? (other than here!)

I am interested in learning where operators who want a 'built-to-last' excavator attachment first look? Is your first call to a dealer? Surfing the Internet? Or is the perception that unless manufacturers are exclusively selling through a dealer network then the attachments are likely junk quality. Disclosure: I am part- owner of a quality attachments manufacturer and want to get a sense of where seasoned operators search for information.
