Flydaddy and Biscuit,
Just as something to think about, although the weather in the UK can be much worse than the States for your PPL, you will most likely have to fly in it (proficiently!) eventually when you return (assuming you're from the UK, which I should have checked in your profile first!)
You may find it difficult if you havn't done anything other than sunny skies / 5 gusting 10 headwind throughout your PPL. This might cost you far more in your training later when getting your skills up to standard before the CPL.
Yes - the PPL is more expensive in the UK. Just make sure you factor in the added value from the more challenging boundary conditions.
Andy.
