I was wondering where I can find some electric converters that you guys use at the island. Is there a good website or a any store you guys would recommend. Do I even need electric converters from 110 to 220 for the island? thanks

It depends on what you are looking for - if you are looking for one for your laptop, its unnecessary because laptop will convert 220 to 110 (just check your power source to make sure that there is a built in converter)
As for plugs, there are standard British outlets here - so if you plan on bringing anything, bring that.
If you are planning on bring other appliances, be wary of being taxed when you enter the island - they can and will tax you on all appliances that you bring. That includes alarm clocks and coffee makers, etc.
Other than that, just bring the British converter plugs so that you can plug standard US plugs into wall sockets.
My suggestion would be to go to Radio Shack and get the necessary equipment - they're usually pretty helpful - just tell them what you are looking for.

Radio Shack is definitely your best options. Just tell them that you need European converters and they will be more then happy to help you find what you need. If you do bring electronics on the island make sure you don't keep them in the new box, open it up and take them out otherwise they will be taxed.
