I've had a Hayter Harrier for about 10 years which I chose after reading a Which report. Lawn is about 70' x 30' so I didn't go for the biggest version they do. You'll need something fairy wide or it'll take you ages. It has adjustable height, variable speed, is not too difficult to start with a pull toggle and pulls me around the park pretty reliably. I've found it easy to get serviced (unlike a previous mower I had). My lawn isn't bowling green standard but it copes with the uneven surface reasonably well.
We have just replaced our old Hayter with the same version Harrier 48 Electric Start & Variable speed. It can mow close if you want it to. We have a large lawn too, about 1 acre and do the half nearer the house with the Hayter (it's v bumpy thanks to Mr Mole), and the further end has a rougher finish with a ride on, plus a "wildflower" area to hide the septic tank! The Hayter is fine, and easy for me to use with my dodgy shoulder!
