Wtf is geocaching ? 

its also something to keep the kids occupied when we go out, instead of them sitting in all day playing bloody Xbox's and ds's, t.v's ect ect. It looks fun

Thanks for the input guys, but the reason why I mentioned a stand alone GPS unit is because I want to get back out doing what I like best, walking, hill/mountain climbing ect ect (obviously it wont be used as a sole navigation device), so therefore I would like to have a stand alone device used for both things.
Using a mobile phone for this is not viable for me, due to weather conditions, risk of dropping it, breaking it, losing it, mobile signal problems, GPS accuracy problems ect ect. I don't have the privilege of owning such an inferior, overpriced crApple gayPhone or IMO, a crappy Gaydroid device, Im still using my far far superior Nokia E6-00 running the now defunct Symbian OS, and has a far far superior battery life than any phone out there at the moment, even though it made it's debut back in 2007/08.
I've been looking at the new series of Garmin Etrex, the 10, 20 and 30, its the 10 that's caught my eye at the moment, it has all the features that I need for doing both things, but with a price tag of around 100sheets, I would certainly pay that as I know I would get my money's worth.
I know it's easier all round with a smartphone but it's just not viable for me, for the reasons above
