Hello!
My husband is kinda the same, he always says he doesn't want or need anything when it comes to what he would like for christmas, so this year I have bought him a radio controlled helicopter come flying bug thing! I know he will love it as it is probably the last thing he would expect but one of the things he would like but never buys (if you know what I mean)
I got it from
http://www.firebox.com lots of good gift ideas for blokes (and woman too as I am a bit of a gadget lover)
