I have come across multiple websites offering bitcoins for UK bank transfer. What site have people had the best experience with?

I've come across a few so 

[www.quickbitcoin.co.uk](http://www.quickbitcoin.co.uk "www.quickbitcoin.co.uk")

[www.bitbargain.co.uk](http://www.bitbargain.co.uk "www.bitbargain.co.uk")

www.blockchain.info

Ideas?
