It's time again to replace our mascara, and once again we are struggling with the decision: drugstore or luxury?

Today's choice is between a return to the reliable and affordable Maybelline Great Lash in Blackest Black, under $5 everywhere, or upping the ante with a trip to Sephora for Dior Show Black Out Limited Edition, almost five times as expensive at $24?

Everyone knows that you should put out as much as you're comfortable spending on high quality base/concealer/face make up. But mascara is open to discussion. Some experts say buy cheap and often, others say that the only way to avoid Liza-like raccoon eyes (assuming you're not going for that look -- sometimes we are) is to splurge on a big name.

Which way do you sway?
