I have a 2000 model with the Primo Nido bassinet and the Ganciomatic carriage attachment that my 2 1/2 loves for walks. We're expecting baby #2 in May and would like to get another chassis for the bassinet so we can go for family walks. I looked on pegs website and did see a chassis, but I don't know if these will fit. I e-mailed them over a week ago and of course haven't heard back. Any ideas on where else to look and about how expensive they are?? Thanks!
