This is so useful! Thanks. I've seen my Dr today as I fear I have early-onset PAM-mania caused by a desire to own my first one. There's no cure; just a slow descent into pennilessness with a noticeable swelling in the watchbox area!
I'll be pulling the trigger on my first one shortly and this guide and your excellent thread describing the different models are helping me to make a considered choice.
Thanks, will try tomorrow
