You'll probably get more replies about this on the pushchair board.
I second the peach jogger, but as melliebobs says it is expensive. Btw, I think the Jane may have been a slalom or Powertrack.
Do not get a buzz. I have no idea why they're so popular (or why I bought one) as it misses the mark in pretty much every aspect!. Avoid!
But if you want a 3 wheeler with a reversible seat there aren't all that many options. The iCandy peach jogger, jane slalom reverse and out n about nipabout are the only ones springing to mind at the moment.
However, if you would compromise on something where you can use a carrycot till around 6 months and then would have your LO forward facing, then there are many more options. I'd be looking at mountain buggy, easywalker and baby jogger models. Something like the mountain buggy swift or urban, easywalker sky or baby jogger summit.
Also consider 4 wheelers. I think it really varies on what people prefer, but I'm a 4 wheeler person, even for off road, as IMO they are much more stable and less tippy. Look at the Easywalker qtro, the new baby jogger Versa (due around summer iirc) and Easywalker June (due in June/July).
Good luck, pushchairs are an absolute mine field!
