Twiglett - we've just bought the XT and it's very nice! Lovely and light (easy to push one handed while holding the hand of older child while crossing a road - invaluable for me!)
Only quibbles are that the basket isn't very accessible when the seat is down flat, and adjusting the seat height seems a bit flimsy... otherwise it is ACE. Best pushchair I've owned (and I think I'm on number 7 now.... )
Bought ours from the Glasgow Pram Centre btw, and can recommend them highly.
