I'm new to the two-wheeled world so please be gentle

After 10 years spent sitting in cars in traffic jams, I've decided its time to move over to two wheels to save on time and fuel. I've just done my CBT and am now looking for my first bike. I was initially looking at the Honda Varadero but my budget is only about £1400 so its difficult to find a good one in the South East for that kind of money so am now considering scooters. I will be doing quite a lot of miles so am ideally after a decent sized 125 maxi scooter but don't really know where to begin.
I've been looking at either Honda S Wing, Suzuki Burgman, Yamaha X Max, Piaggo X8/9 or Peugeot Satalis. I'm leaning towards to Japanese makes as I've had French, Italian and Japanese cars and you can probably guess which ones have had no end of issues and which have been indestructable.
The problem I'm having is finding any real world comparisons between them, the all seem to have good reviews from their own owners but not many people seem to have riden more than a couple of them to get a fair comparison. I'm hoping to have some free time in the next couple of weeks to find some at local dealers and get out and test drive them but any help or advice you could offer would be much appreciated.
I'm a tall guy but am pretty skinny so don't add a lot of wait, I want something that will happily sit at 60-65mph but will still hit 70 to make getting past lorries etc a bit easier. My main concern is comfort, some days I might do 40 miles each way so need something comfortable. Most of it will be congested dual carriageway or B-roads so don't need a lot of top end speed but don't want to be dangerously slow either.
Sorry to bombard you all with quite so much reading this early in the day.
Regards,
Ian
