Once you have added to your basket, make sure you select 'BUY NOW & SAVE! VOUCH OFFER [price -£50.00] -SPECIAL OFFER-'
These seem like a bargain to me. As said, loads are available at the moment.
I have checked several machines, and some list Bluetooth, some don't so double check before buying.
EDIT: Make sure you chose one that says 'LCD Back Cover Black with WWAN'. These have built in Mobile Broadband, and can be used with any SIM card!
Not as good as last time, but still a decent price :)
