I have a P&T Vibe and I absolutely love it. I don't know why it would be said that you need to hands to put the brake on as it is a single button right at your hand, very easy to put on. It is however a little more difficult to release, which I personally think it s good thing. You can do it one handed but it does need some practice... I have it down pat now

I have Anelise in the back toddler seat now and Harrison in the front. I only carry a small back pack with me in the pram in the basket and leave the big nappy bag in the car.
I have found that most of the accessories for the P&T's are expensive as you said, but I got a great deal through babies galore which included the sun cover & a rain cover. I have never used the rain one.
