Consumer Reports tested 64 oven ranges.

"We tested electric, gas, and dual-fuel ranges," said Consumer Reports Bob Markovich. "One feature we looked at in particular is convection ovens, since they're touted so heavily by manufacturers."

Convection ovens are supposed to speed up roasting and make multi-rack baking more even. But they can also be pricey-are they worth it?

"First came convection ovens with one fan, then two fans, and now three fans."

Consumer Reports decided to have a cookie bake-off to determine whether more convection fans really mean better-baked cookies.

Samsung claims it's "three-fan true convection system cooks food more evenly." Consumer Reports pitted it against an LG range with two convection fans, and a Jenn-Air which has one. The challenge: baking three racks of cookies at the same time.

"The Samsung did a fine job of baking all three racks of cookies evenly. But so did the other ranges with fewer fans." said Markovich.

The bottom line: more convection fans don't necessarily deliver better baking results. Consumer Reports's tests show you don't necessarily need a convection oven at all to get perfect cooking. So you can save money there, too.

Consumer Reports' top-rated electric smooth top range doesn't even have the convection feature. It scored very good in baking and is a Best Buy. It's the Kenmore 9641 range, which retails for $750.
