I wpuld go for induction instead. Gas ranges are inefficient and lower the indoor air quality by a lot. If I wasn't renting I would change the gas range I have with induction immediately.

Having said that, almost all gas ranges are BIFL. If you are still convinced for a gas stove, look for one with a very sturdy inox plane and normal, standard and replaceable, parts. You want one with the security check (checks if the flame is active, if it's not it turns off the gas supply) as those are considerably safer.
