Need to buy a buggy board since I sold my double P&T and DS1 who is 3 won't walk very far and I'm sick of driving around everywhere! Anyway, I'm thinking that a Lascal buggy board is the best? But there seem to be many diff types on Ebay. I want one that is cheap (second hand is fine) but that is easy to attach to my McLaren buggy and can fold up when not in use. Help please!
