Here are some for the guys, I don't know any that don't like tools!
Great Gift Ideas and Handy Things for the House!
And one for my oldest son - Automotive Tools! He is an automotive genius, all I know is he can fix or figure out pretty much anything mechanical! (Sorry, link removed, it appears that tooliday no longer has a separate tool special for automotive - updated 4/5/11)
I even found a great soldering iron for myself on one of these sites, one day! Woo Hoo!
