Well I got my X800XT last Friday though this is the first opportunity to post. It may have been mentioned here before, but Tekheads (www.tekheads.co.uk) do an e-mail notification when things get back in stock and that's what let me nab one. My phone picks up my e-mails and I got notification last Thursday morning that they had some back in stock. I logged in straight away and had an XT the next day. Unfortunately I'm working away this week and don't get to actually plug it in till next week :-(
However, I can thoroughly recommend both the "mail when back in stock" and the speedy dispatch of Tekheads. Happy hunting all.
