Davros, I must an old bag too because if I had the money and the space, I'd get one of those gorgeous old fashioned silvercross coach built prams that cost about £7/800 from Harrods!
Misdee - I'm trying to avoid getting more than one pram, that's why I don't mind if it costs a bit more to begin with - we just don't have any storage space left as it is
Jibberjabber - i did notice the Stokke was the only recommended pushchair on a bad back website today, and it did make sense to me (I suffer from an old lifting injury now and again). I can imagine your Stokke causing a bit of a stir - I remember when Bugaboos did that a year or two ago, now they're all over the place. Is it any good off road (ie country lanes that sometimes get a bit squishy in the rain?)
As to the Matrix's safety - I think there was a Which? report that failed all the lie-flat carrycots that you could attach in the car. I think the Jane Matrix, however, passed lots of tests with flying colours as it is a proper car seat rather than just a carrycot.
Portree - it's good to hear you don't find yourself using your Triumph much - a few people have told me I'd find the Jane 3 wheeler too cumbersome and would end up using a lighweight umbrella type stroller instead.
Lockets - I've been looking today (on line anyway) at the new version of the Jane Pwertrack 360, it's called the Slalom, and has a brand new front wheel, so hopefully there won't be any problems with this one. Not heard about that problem though myself - at least they're guaranteed!
