The following is a quick list of suppliers of low cost laser engravers. I don't know the best way to maintain a list here, but if people find other suppliers with websites, seems like this would be a good place to put them. This list is not an endorsement for any of the websites or suppliers, just what I have stumbled on or been lead to...
