Hi there Mappers!

I would like to start giving my contribution to the community. I would like to find a decent handset, not too expensive, possibly to fit on the bike, although this is not strictly necessary. I would like it to have a screen and be Mac-friendly. To be bought in the UK.
I checked the wiki but can't make up my mind, as I don't know the differences in the handsets.
Any suggestions?

Thanks guys
