These UK addresses are only processing companies. A few other casinos use these too.
I can now speak from experience, and in theory there DOES appear to be an opportunity to "abuse" the currency edge as the bonus on sign up is $125 or £125. Although the casino charges this 5% if you are not UK resident, my withdrawals are in GBP rather than USD, so there is no conversion charge at Neteller.

I do believe, however, that the issue of how currency is handled at some casinos needs clarification. Often what you see is not what you get due to behind the scenes currency exchanges.

I have just tried Intertops, and GBP is allowed for me. When I deposited, it exchanged the currency to the base account USD, however, my Neteller was deductd in GBP and no "leakage" of funds was experienced.

If you are to be charged 5% for having the account in GBP, it might be better paying for the exchange at your end and registering to play in USD. Main Street will not then take a 5% cut, and you will pay around 2.5% at your end, maybe less if you open an eWallet account in USD and pay the exchange fee once when funding it for all USD casino accounts.

It's a shame I can't have two Neteller accounts, one in GBP and one in USD, it would save a little in exchanges as I like to keep my money on the move as this seems to make the casinos a little hotter.

I am impressed by the Playtech slots, I have been playing slots only and have not lost a dime, in fact I am ahead! This would be pretty unusual at MG without a big hit or two. The only downside is the software occasionally freezes solid for no apparent reason, usually on slots autoplay.
