What is the best GPS Watch for running??

I've had nearly five years very good service out of my 305, but having recently lost my HR strap (left it at a race I think!) I've decided to finally upgrade.  Have been reading this post with interest and I think my options are narrowed down to the 410 and 610.  Money-no-object I'd definitely go with the 610 but it's a LOT of money. 

Main advantages of the 410 over the 305, for me, from what I've seen are:

- smaller, more comfortable.  Not fussed about wearing it as a casual watch but the clunky 305 was never entirely comfy on my bony wrist.
- improved satellite reception (clever GPS that locks on to satellite reception in your usual locations more quickly)
- improved HR strap (I'm often frustrated that I can't record a true max for an easy run for example, because the 305 obviously thinks that one of the earlier spikes is a true reading)
- more sophisticated interval training options - you can mix up 'distance' intervals and 'time' recoveries, right?

I've got a big birthday coming up, so I may just put up both options of the 410 and 610 on my wish list and see which one my well-to-do bruv wants to get me. 

If he gets you both, can I have one?

Yes, should that happen you can definitely have one! 

phil, i'd debate the "improved satalite reception" part, the 305 side by side with the 410 almost always performs better, its marginal but still. dcrainmaker did a test with them all running at the same time on the same runs (pre 910xt release) and the 305 was top on almost all the tests,

ah, i just re found the test and it was the nike + gps, ironman timex, garmins - 305, 310, 405 (not the 410) and 610, my mistake. 

Hi. I'm looking to buy my husband a GPS watch for Christmas (Hope he's not reading this!) I've looked at the Garmin Forerunner 405 for £120 on Amazon, is this recommended by you seasoned runners? I'm not a runner myself so would appreciate some guidance.

My husband regularly takes part in half marathons and trains by running different routes around our neighbourhood, timing himself on his 'normal' watch. He finds the information provided online from his chip after his offical runs very useful so I thought that this type of watch would help him be more informed about his performance and the virtual trainer feature would be an aid to his training.

Do you guys have any (kind) advice or comments?

Love my clunky Garmin 305 - you can get a velcro strap for it which makes it feel a little less clunky.

410 owner here. Very happy with both it and the Garmin online software. I'd recommend it over the 2-- models and on current prices it's a bargin.
