I had noticed that alright: nobody talks about Seac here, but all European stores carry it. In any case, cheapest I found was 377. On Amazon (no special warranties here) it's 600.
I think at the moment it's the most economical option for WAI and compass and watch size. If it's $77 over Goa, I'd say it's a contender. And I'm not sure what Goa/Newton have for log download: for ones that don't come with USB or BT built-in, it's typically a $100 extra.
Given the failure reports, lack of extra warranty is a downer though...
