I was one of the "I hate the P&Ts" gang until recently when I bought one out of desperation for my two DDs - the tandem I bought was terrible. I bought the Sport - couldn't justify the extra $$ for the Vibe. Having said that, the brake on the Sport really is awful - its very jerky and stiff to get on and off and it usually wakes DD#2 because of the way it throws the pram around a bit - and that is one of the improvements on the Vibe. If you're not planning on doing what I did and having two very close together, and therefore needing the toddler seat of the P&T, I would recommend paying that little bit extra than the Vibe and get the Mountain Buggy instead. Its what I had for DD#1 and it is sooooooo much better than the P&Ts. And I would definitely not compromise and get a cheaper pram than either the P&T or the MB - having done that myself and ended up getting the more expensive pram anyway, I really do think that you get what you pay for.
