My SIL has a Steelcraft something (sorry - will find out the model name!). She says its great for shopping and stuff because its really light, so easy to throw in the car. She says its not good for walking though. From the prams/strollers I've had a "drive" of and what girlfriends have said who have them, if you want one for decent length walks I wouldn't touch anything that doesn't have pneumatic tyres (which are obviously more expensive!!)

ETA - I would definitely get one that can lay back. A girlfriend's bubby is 12 months older than our Izzys, and she still sleeps a lot when we go for long walks together.
