I don't know if you've seen the ashtrays that Forrest ( @R1100RS ) is making, but they are beautiful; truly works of cigar art and great conversation pieces. That's something the wife could appreciate and you could take pride in.

In your price range and as suggested, a Ronson is probably your best bet, if you want a torch. Otherwise you could get a Zippo with a butane insert and have a very nice lighter for not much dough.
