I am in the UK and received mine on Tuesday of this week from Go Outdoors, complete with 1:50k OS maps. It arrived just in time for 2 weeks of hiking and sea kayaking in Scotland :-)
Wow great news!! GoOutdoors need to update their website to show the 600 is available then and not still on pre-order! (I'm still waiting for a 650 though, and will be buying from Cotswold Outdoors as their prices are better with the GAGB discount)

I'm also intending to wait for the 650. I'm not currently a member of GAGB, will I still make a saving with joining and going to Cotswold Outdoors compared to GoOutDoors? Keith
