I've got my DH "Bop It" - it's a game he's been looking for FOREVER after we played it at a party. I'm also thinking about having one of our wedding photos put onto a huge canvas for our living room, but undecided about that so far (would kind of be a present for both of us rather than him LOL).
Does he have an MP3 player? You can get fairly cheap and small ones now, DH got me a Creative Zen Stone last year - a pink one! - perfect present! I'm not suggesting a pink one for your DH but I thought it was a pretty cool gift
Maybe a magazine subscription or a voucher for something cool he's always wanted to do?
