Cheers thanks, i have found the turmoil on what looks like a UK website but its charging over double at the conversion rate
(£100-$200 ish i believe)! They want £276.95 for the rolling chassis, and over £400 for the one with the engine.

I also checked out the thunder tiger looks like it might be worth more of a look into. I can only find the EB4 S2 in the UK and not he S3 is it quite new?
