Thanks everyone, i have heard nothing but glowing reports about the Maxi Rider so am biting the bullet and going to buy it today.

Have also decided that once we decide to turn DD2 around we are not going to bother turning her seat around, i am just going to go and buy her one too and then sell our turn-a-tot.
Keep your the guy is working today to fit it, not sure i can wait until next week...
