I've got the Polar RS800sd - nice Not kind on the hip pocket though.

It's worth working out exactly what you will and won't use and shop around. I think they bring out new models every year so might get some on sale when new ones come in too.

I bought mine over the internet and saved hundred - I ended up buying it from the USA though so you might find it cheaper locally!

Still working out all the fuinctions though! Good to get one when you have time to really learn everything it does. I feel like I've been wasting mine a bit so far not yet using everything I could!
