G-SPOT.. $1 a gallon? i'd like to know where is the US you are, as 100LL is $3.50 - $5.00 a gallon in the US...
Plopypoop, just go and train in the US - it's a damn site cheaper - even if you do come home and convert... You'll experience how aviation should be - they invented it after all - and it'll open your eyes to just how snobby/elitist flying is in the UK.
In the US you can just start up, take off, decide where you want to go, land (free in all but the largest airports - even if they're holding a couple of heavy jets for you), borrow a courtesy car while the fuel guy is filling you up (airports are like gas stations - you can pull in whenever you like - none of this PPR nonsense), get a burger, repeat....
Of course, you'll not impress anyone over there by being a pilot, as it's seen in the same light as cab driver/truck driver/pool cleaner... and probably pays less.
