Hello all, thanks for the bump, I'd almost forgotten about this post! :) Pushchair has arrived and so far its all going well.
Good points:
Well, the 1st good news was that the import duty wasn't as much as I'd expected - ended up being £40, so it cost about £950 all in! Bargain! 
It is very very good. Very sturdy and quite easy to push (once you get going and wheels are going the right way - if you have a pushchair with a swivel front wheel you'll know what I mean). Although it is a bit heavy, esp with 3 kids in - I feel like I'll get a workout pushing it.
Its smaller than my Phil and Teds and sits very neatly in the hallway.
All 3 children have (so far) been happy sitting in it.
I've had nothing but positive comments about how good it looks. (With the buggypod I had a lot of negative comments! :( )
Bad points:
The middle seat isn't ideal, but I either put the smallest baby, or the one most likely to sleep in it and that way its been fine.
It isn't easy to get the child into the middle seat with the front seat on, but the front seat pops off easily (2 metal snibs allow it to slide off) and its also very easy to reattach once the middle child is in.
Its big and a bit clumsy to store when folded - but not impossible.
I think thats the main things... I don't think its quite as easy a single/double as the Phil and Teds (raincovers more fiddly for a start), although the storage is far better... but as a triple its as good as it gets I think.
I've only needed it 1 day per week so far, so have been using my P&Ts the other days, but from next week I'll need it 4 days pw, and I have the feeling that once I start using it more I'll probably use it all the time (through laziness if nothing else!) :).
Any other questions let me know though. :)
