If you're not sure what to buy as a gift then give them a gift certificate.
Dive-Logs Gift Certificates make great gifts if you are not sure what to get as a present! Give the choice along with the gift - particularly for personalised items such as Log Book Stamps and Scuba Tags!

Just like to reply and say thanks for the astonishing service you have
provided, this courtesy e-mail is the icing on the cake. Rest assured
you'll have my business again and both my dive buddies are now perusing the
catalogue you sent, for a stamp of their own.
Good luck for the future.
