The highest "real" ones I've found:
Siliconware (SPIL). Before Thursday's crash, it was around 14%. At the current price, it's almost 20%. It almost seems too good to be true, but I haven't been able to find a single thing anywhere online disputing that it's legit and real.
Williams Pipeline Partnership (WMZ). "Only" 10%, but unless there's something lurking in the shadows I'm not aware of (and if there is, I'd really like someone to point it out before I go nuts buying it), this company looks pretty solid. No debt, healthy revenue. Their stock price itself is pretty flat (it went from ~$20 in April to ~$13 last week, with an all-time low of ~$10.50 in October), but with dividends like that, their long-term share price is almost irrelevant. Check out the graph of their stock price over the past week. Thursday & Friday's crash barely made a dent in it. When the price went down, its owners mostly just dug in and quit selling.
BP is pretty tasty at the moment. "Only" ~7.5% dividend, but their stock price is unusually cheap at the moment because it's a British company, and the Pound is pretty low compared to the Dollar right now (compare their price to XOM and CEO to see the difference the exchange rate can make)
I'm fond of Maxim (MXIM). Their dividends aren't shockingly high, but they're still pretty high, and this is another company with no debt and abundant cash reserves. It's also one of the few companies in an industry that I actually understand (they make some REALLY cool mixed-signal ICs that are about as close as you can get to single-chip solutions with nothing besides a few passive external components that aren't cost-effective to put on-die, like capacitors).
Verizon (VZ) is another company that's been reliably stuffing dividend cash into my bank account for years.
Pfizer (PFE) looks good, too. If stocks crash in December, it's near the top of my list of companies to buy into ;-)
