The BlackBerry Z10 is a new phone on a new platform and it’s a great piece of kit. I’ve currently got one which I posted my initial impressions earlier on in the week which you can read here. 
Up until now it had only been available through the networks. But now retailers have started to get stock. Starting with Expansys. Costing £519.99 including shipping. Which you can find here.
Spec wise the Z10 is really quite good.
