I'd drink my own piss before I drink Coors.
Don't know if this is exactly what the OP was getting at, but some nice debunking of recent claims of icky ingredients in beer.
FWIW, if you don't mind dropping a few extra bucks on beer (think of it as buying a bottle of cheap wine) check out Kentucky Bourbon Barrel Ale if you can find it. $14 for a four pack at Whole Paycheck. Maybe get the rest of your beer needs at Trader Joe's ($6 for a six pack Naragasset tall cans) to even out your budget.
