Same as John here, I don't collect anymore but will go for a stove that grabs me; the others I've got.
Tilley lamps? The older ones are better quality than the newer, and Vapalux seem to have just maintained a great standard throughout its history so for me the better choice.
Vapalux or Bialaddin go for not much coin on eBay, don't worry if they look a little rough, a service will put them right easy enough. Remember that a Tilley or Vapalux give off around 1Kw of heat so will help warm a
well ventilated tent in cold weather (at your own risk).
All this talk of paraffin/kerosene lanterns ignores Coleman lanterns, but don't, use clean fuel and they are also great to use (Coleman do make paraffin lanterns).
Great thread and good to see it here.
