Re: Suunto Core and alternatives
Definitely have a look at the Lumi BikerFool - seriously nice watch, and you forget about the weight about 5 minutes after you start wearing one
I actually seriously considered the Lumi, even though 'tis a girl's watch, on the basis that it looked a bit thinner than any of the other Core models, and it is a much nicer design. In the end I held them both up side by side and they are about the same size. Much nicer looking though - if I could swap the strap (which is very girly) I would still like one.
My X Lander had a dodgy button once so emailed Suunto and they collected it same day, took it to Finland, fixed it, bunged a new battery in for free and returned it within 4 days. Smashing service so stick with it RoddyP - I'm sure they'll sort you out.
That said, my only criticism of my Core was that the Altimeter went a bit off-campus on the one and only time I took it over 6000m. Up to that point it was fine though.
I think these are more than a gadget - especially on the bike, if you know the next hill is XXm high, they are great for pacing yourself and psychology ("only 100m to go" etc!)
