I'm looking to buy bitcoins using GBP. So part of my question is: is there an exchange that accepts GBP?

All of the exchanges I have seen seem to rely either on trust or on Liberty Reserve. I hadn't heard about LR until today, and a bit of googling appears inconclusive as to whether it is a scam or not. So the other part of my question is: which exchanges are trustworthy, and is Liberty Reserve a safe conduit for buying bitcoins?

So, as someone looking to take some GBP and buy some bitcoins, can you give any advice on a exchanges that are not scams, particularly if they will accept GBP directly?

Thanks! :-)

Thanks. Yes, it does seem a good idea to steer clear of LR.

Trading directly with other bitcoiners on IRC is an option, but I suppose I was hoping for something that looked established and trustworthy, rather than trading with an anonymous individual.

#bitcoin-otc has a rating system so you can find out whether someone is trustworthy or not. You can see that here: http://bitcoin-otc.com/viewratings.php. I'm new to bitcoin, but from what I hear, people highly recommend #bitcoin-otc and trust it alot.
