Currently doing my PPL
As others have said, take a flight and see whether you like it. If you decide to go ahead, do a good deal of reading in advance - buy Pooley's air training manuals or alternatives.
It's not that the ground school work is particularly difficult, but there is quite a lot of it and even with a background in radio control and physics, I've found that I have had to work fairly hard on it.
I asked the same question as you a little while back, and eventually went for training in the UK, but received many good reports of ETF. Having said that, I didn't like Florida when I was there in the past, and I would wager the flying experience I'm getting here is both more interesting and better preparation for flying in the British isles.
