[Home Repair] Source for porch lights?

[M A V I C]

I'm looking to replace a couple exterior home lights. We looked at Home Depot. Wasn't really thrilled by the selection. Found some cool lights online, but they're $$$. What's a good site to look at for such lighting?

Any suggestions on things to look for or stay away from? We want something with a silver/light metal finish - not chrome, black or bronze.
