Wallyworld used to carry Lamplighter Farms lamps which were fairly well made but it's been 20 years since I bought a lamp there so who knows what they sell now.

Give a thought to fuel storage. A gallon of lamp oil will get you through a few days of a power outage (depending on how many lamps you're using) but if it turns into a couple weeks (like large parts of Oklahoma after their last ice storm) you'll need more and a safe place to store it.
