Hi John
I've found the 305 reasonably robust. I broke one by dropping it onto concrete (duh!) but apart from that, they've been a lot more robust than the 301.
I'm also using the 405 at the moment (and will be posting a review shortly). The 405 is a cool gadget but it has a touch sensitive bezel (like the ipod) that does not work well with wet fingers. For that reason (and the larger screen of the 305) I'd recommend the 405 for runners/multi sporters but the 305 for paddling.
I have been sent some pics of a 305 where the rubber buttons appear to have rotted but I've never seen this on a unit here in SA.
Cheers
Rob
