I can totally sympathise Lisa ...my DH is 30 this year too and I had terrible trouble trying to work out what to do. He's so hard to buy for, and I wanted something special ...but he's not someone that really keeps stuff - ARGH!
I had a wee brain wave last week ont eh way to work (yes, that was the big flash of blue light at 7.15am on Thursday) and bought him a number plate - UHOH30!

since he's whinging about getting old
It was a bit pricey at $699, but the whole family has gone in on it, and since his bday is just before xmas it's a joint xmas and bday pressie.
