Domain name purchase and escrow

[.Flyer]

I am purchasing a domain name on behalf of a client. The current owner is in the US and is selling for $350US. For security reasons, I'd prefer to use an escrow service (unless there are any alternatives?). Does anyone have any recommendations?

I've looked at escrow.com ($25) and sedo.com. Sedo is more expensive at $50, but looks more professional as they are geared up for domain name selling/purchasing.

Anyone used either of them or others?

Gone with sedo, hopefully it will be a smooth transaction.
