I have just had a really good experience wth a kind company and wanted to share it. We use engraved ID tags (large dog tags basically) attached to DS's clothing with his name and our phone numbers on it (and the information that he cannot speak), and I recently needed to order some new ones. I used a company picked at random off eBay and they were just so nice. The tags came with 36 hours if my placing the order, were high quality and prefectly engraved, and some sweet person had tucked a (real) lucky sixpence in with the tags, which came in a little cloth bag.
I was really touched. So if anyone wants some engraving done, these are nice:
