Alert: Dad's Bday Sunday!!!

We are totally baffled as to what to get my dad for his birthday. Here's the run down on info for him.

• Turning 59 yrs old Monday (but acts like he's 45-49)
• Is a dentist (tho his first profession was engineering)
• Quiet & reserved
• Has a girlfriend of almost 9 months
• Likes cars & racing
• Loves scuba
• Likes sun and beaches
• Likes music and movies, but neither watches movies or listens to music (go figure)
• Has too many clothes from past gifts
• Likes gadgets but doesn't need watch, iPod, computer, printer, camera
• Procrastinator--he really means to get stuff done, but doesn't....ever, very rarely
• Recently started cooking every now and then with his gf
• Doesn't read

Keep in mind that my sisters and I are poor.

We bought a picture frame for him that we are going to do up, but we don't want that to be the only thing since its cheesy. We can't spend a lot, don't want to get something huge, but something smaller he'd still enjoy....and not just let the dust gather as he does with the vast majority of presents besides clothes.

HELP!!!!!!!!!
