Welcome to JC! This type of gift is difficult to come up with...I have been trying to find the perfect gift for the pilots in my family my entire life! I know several other people have mentioned headsets, if you choose to upgrade there are a million opinons out there (but, I just bought a set of Lightspeed active noise reduction) for about $500. and i LOVE them!
another idea...maybe a new flight bag, or even great pics of airplanes framed....hand held GPS, hand held radio. Look at sportys.com they always have all sorts of gift ideas
