I'm going to try the barclays "pingit" with https://blockchain.info/
You need a smartphone though for the app, it's basically just sending money directly like you normally would to Mt.Gox on the barclays website, except you use this phone app..there's no extra fees either. Won't have the cash for it until next week though so if someone else wants to try it and report back..
I tested it by sending a a tiny amount of bitcoins to my blockchain account and then back, worked fine.. good enough for me.
