I think if you're ever in danger of catching the sticker on fire you've got bigger problems. I've had my torch for maybe 16 years, the base doesn't look bad at all (except the silicon feet have been missing for many years.) I don't know how/when the sticker disappeared, but good riddance. You're not really using the tool properly if you're primarily looking out for the resale value.
I'm glad you're happy with your new torch though, now go melt some glass!
