Well sorry about this but I must disagree with you here. Lets be honest, the costs in the US are 50% of those here. Having trained in both the UK and USA I would recommend anyone to train in the USA!
By all means take a few extra lessons here to make sure that you are happy with the environment but remember that we should be flying in good weather - as PPLs, we are doing this for pleasure.
As regards costs, well 3,000 pounds is a lot of costs savings and more than pays for a few extra lessons when you return here to make sure you are up to speed.
