I have a gas stove, but since I do not use its oven I don't really care about it.
Keep one thing in mind with gas stoves though: make sure you do not need a match to start it, based on the following thread viewtopic.php?f=1&t=14646&p=87538&hilit=stove#p87538
My dad does use his oven often so he bought an electrical BOSCH oven. When I asked him why he bought an electrical one when gas starts faster and is cheaper, he said that with electrical ones, he achieves an even heat and better broiling. His stoves are gas operated though, he bought both parts separately.
BOSCH is located in Monterrico, Surco: Av. El Polo 869 - Urb. El Derby - Surco
Sunflower: regarding the correct word, I've read it is described as "burner".
