Christmas Presents

So christmas again and I'm forced to once agan struggle to find something to buy for my dad, as usual I've left it until the last minute.

I was browsing ebay a little while ago and found a Garmin S1 approach watch which looked pretty good (if you haven't seen them they're just a golf gps in a wristwatch with a few other features) and it was going at about £140 which is pretty cheap for one, but I couldn't seem to find any helpful reviews online. I went ahead and bought it anyway but I'm just wondering if anybody had ever used one before and if so what they're like?
