It may be obvious that I would post this, but if you can get Recaro seats for your car they do make the difference - a bit of decent head restraint for hard corners... :-)

For some reason we ended up with 9 buggies/strollers but they are all good for different things. We have a great Graco which is good for holidaying as it folds and unfolds with one hand (so easy for taking through airports) and doesn't sink into sand very much. We have a 3-wheel off-roader which was great for taking the little ones hiking, and a McLaren 'umbrella' style one which was very simple and light once they got a bit bigger.

The Britax system we got for our first baby was very reassuring, but ultimately a huge waste of money, heavy and clunky.
