Yeah ... I have used a couple over the last couple of years.
Try
www.hymarkets.com
They are web based like you asked, they have very good customer service, they are regulated by the FSA in the UK and you can trade all financial markets from their platform not only Forex.
I would reccomend a Gold or Premium account as the spreads on the Mini are a bit above avarage. On the other hand they don't charge any commision or any fees on deposits or withdrawals so that balances out.
In addition to wire transfer they also accept credit cards and even PayPal which is prety cool.
You can be up and running in a few minutes.
