SuperCheap Cast Iron OK?
A local thrift store has a stack of 10" cast iron skillets and grill pans marked with a $5 price tag. The construction seems solid, if uneven (some in the stack have rough spots on the handle, etc.) and the cooking surface is smooth, smoother than the Lodge pan I bought recently and love. They're heavy, even a tad heavier than you'd expect for their size - I've concluded they're "real" cast iron, but were made with a thicker mold than Lodge uses.
So, does anyone know if there's a downside to buying cheap cast iron?
