My apologies if this has been asked before, but I couldn't find it anywhere...

I was just wondering if people could tell me a bit about robotkingdom.com. I asked about Hobby Link Japan not long ago and got some great advice from people on this forum (I've since used them and been very pleased with their service and prices), so I thought I'd do the same with Robot Kingdom.

Where are they located? Why is everything in US dollars? What are their prices like (they seem very cheap, but how's the shipping/postage?) Any other comments - positive or negative?

Thanks
