thankyou all so much for your good advice and input, very helpful!
we headed out today thinking we would get the vibe, but after seeing it and comparing them all it was down to the dash or sport, after an hour or so ( i decided we wernt leaving till we had finally bought something!) DH decided he perfered the sport, and thought things were more likely to go wrong with the brakes on the dash.. its also cheaper. i didnt really mind either way. so the sport it is!
all in all i am glad we went with P&Ts, i'm very happy with it, so far its been great to push around the house! can't wait to use it properly!
thanks again!
