I went to Croydon shopping yesterday, to Baby Nest www.baby-nest.co.uk/ and to Mothercare and Babies R Us on Purley Way. Baby Nest is worth a visit - family run independent, very helpful and a friend had recommended to me - they will help you check car seats and buggies fit the car etc. They stock the EasyWalker DUO, Phil & Ted Vibe, ICandy Pear and Out n About Nipper as well as some McLaren and other strollers and a Mamas & Papas twin. Mothercare was a horrid shop Those of you with children already will probably chuckle but I was shocked! However they do have a Mountain Buggy Urban and a double carry cot on display. Babies R Us was rubbish - no twin buggies at all (BTW I am using Buggy to mean any type of pushchair, pram, travel system etc. as I am very confused as to what constitutes which).
I loved the Mountain Buggy - it folds very easy, completely flat and you can unfold with one hand. It's very easy to manoevre even though it is quite heavy. It's pretty big so I'm a bit concerned about whether it's going to fit in the boot, but because it's flat when folded, you would also be able to get the carry cot(s) in too.
I had high hopes for the Easy Walker DUO as this is the only side by side twin I can find that takes Cabriofix seats. Indeed it is a lovely buggy, really well made and sturdy but for me (5'3") just too big, I didn't feel confident to push it around without taking out innocent bystanders! It folds in half quite easily, but it is very big when folded.
The Out n About is smaller, so feels easier to push, is very light, would fit through doors more easily than the other two and folds in half much smaller. However, it didn't feel as well made as the Easy Walker or MB - a bit flimsier and as if it wouldn't last as long. It's supposed to be useable from birth, but to me the seats didn't look as though they would go flat enough or be comfy enough for newborns. I could see it would be a really good buggy for older babies to toddlers.
The lady in Baby Nest also recommended to me one I hadn't considered - the Emmaljunga Twin Cerox 360 which is a very attractive looking pram that can face either towards you or away. They didn't have one to show me as they'd sold it before Christmas but will have it back in stock this month. Reviews I've read of it on the web suggest it might be a bit bigger and heavier so possibly not the answer, but I think worth a look because it has some unique features.
I still want to have a look at the First Wheels City Twin if I can find one, and to try the MB in the boot. I'm also going to visit the A3 Baby Barn www.a3babybarn.co.uk/index.html perhaps tomorrow if they are open.
Hope that's helful! I started to look at cots but decided that was a whole other shopping trip and car seats is just blowing my mind at the moment. Like your idea jerin of getting something that will last longer, but also like the idea of small baby carrier seats particularly as these are my first babies, so anything that will make getting in and out of the car easier will help - so much to think about!!!
