AH.. a subject I know something about.
If your after a good old mower then you can not beat a reconditioned Ransomes Auto-Certes, or the newer Super Certes.
My Groundsmen mentor loves his Lloyds Paladin (he thinks the sun shines out of its ........ )
Now it depends on your budget. I picked up two good Auto-Certes up for £150 each off of Ebay then had them rebuilt which cost me £400 each. But they are now like new and cut like a dream.
You can get a secondhand Lloyds Paladin for £600-£700.
If your after just a fine cut mower and not a multi-purpose square mower, and you are on a limited budget but you still want a new mower then a Protea Mowers are good value. They are only good for the fine cut!!!!!!

The Ransomes Matador is more of a Square mower, with less cutting blade and is no where as good as the above.
