Graco Citisport Plus or M&S Mistral Buggy?

[Frogling]

Help! I am trying to find a lightweight buggy for my daughter Emily, who is approaching six months old. We currently have a fantastic three-wheeler, but it is far too heavy to lug about town or on public transport, so we need something a little more practical.
I have narrowed it down to the Graco Citisport Plus or Marks & Spencer's Mistral Buggy - does anyone have either of these, or any knowledge of them? All opinions gratefully received - I can't make my mind up!

I've got a Graco Citisport - is that the same as the Plus? If it is I'll tell you how good it is!

I think it's the next model they made - a few extras on it, but would love to know how good yours is!

I have a Citisport as my only pushchair - needed something lightweight as there are steps up to our house. I really like it, but I'm not sure its what I'd go for as a second pushchair to use mainly on buses. I use it very occasionally on the bus (tend to walk everywhere) and find it a bit bulky for hauling into the luggage racks. Also its folding mechanism is showing signs of wear (after 10 months). I'd probably opt for something umbrella folding if I had another bigger pushchair (but no doubt you've already considered and rejected that idea!)
No idea about the M&S one -didn't know they did pushchairs.

Frogling - we bought ours when ds was 5 months old nearly 2 years ago and still use it most days. He still sits in it comfortably while we take his big brother to nursery on the buggy board. I don't have any need to use it on public transport though as I either walk to school/shops or drive and I keep a Mothercare £20 stroller in the boot for when he needs a pushchair straight from the car. So your needs are different from mine. But it is easy to fold and open and is wonderfully light to carry. The shopping basket is ample size and I've always found it very easy to use.

Thanks for the advice Fionn & Elliott - I have now decided to buy a Citisport Plus.
