I'm not aware of any resource that focuses on dividend-paying microcaps (or even smallcaps). But with just a little work, we can track them down. I use these two tools:
1. MSN Money Deluxe Stock Screener: screening for stocks with a market capitalization of less than $250,000,000 and current dividend yield of >= 2 will bring a good list to start with. I usually set the screener to return the top 100 matches, and sift through those.
2. Yahoo! News Search: searching for "dividends & .ob" will bring up recent dividend announcements for otc bb stocks that might not show up in the screen (for example, if they have just recently announced a dividend). Here's the same thing for the pinkies. (I don't have a good search to capture dividend news for the microcaps trading on the Nasdaq, AMEX or NYSE. Do you?)
Using those two resources, here is a list I generated of non-financial microcaps paying a dividend yield of 2% or more. It took less than a half hour to compile, including the time to register for the MSN screener:
DISCLOSURE: I have no position in any of the stocks mentioned.
