I need help! I have quite a large lawn and no mower. The grass is growing and I need to get my hands on a mower but I have no idea what is good and what isn't.

The garden is large enough to warrant a self-propelled, petrol job. I have found the Honda Izy 41 which was selected as a best buy by Gardener's World. Anyone any experience of it? Any other recommended brands or models? Places to buy?

Thanks in advance!
