As the old saying goes, " A miser does things twice." I would recommend that you buy the same type of good quality mower that you had.

Yes, I thought that would probably be the way to go, but always nice to have a second opinion!

With a garden your size you definitely need one Honey, I would ignore the cheapo ones, when mine broke a couple of years ago I was amazed when the lawnmower man said " Oh we don't bother to mend them anymore because the parts and labour too expensive, we always tell customers to buy a new one". I went out and bought the newer updated model of the one I'd had before, hubby bought a petrol one last year when he was cutting the lawns for me, wouldn't listen when I advised getting the narrower lighter version, consequently it sits in the shed and I am back to using my electric one, don't care what he says I know mine does the better cut and I should know after all the years I've been mowing lawns, lol.....

You are of course right Lincslass, you just can't tell a man anything, with apologies to the men on GOY who are of course gardeners and therefore a different breed! Non-gardening OH types always think there is another way than the tried and trusted ones that work. Hence the demise of a young almond tree which got run over by OH with the ride-on lawn-mower in a tight space!
Went with grown-up Son to inspect some of the lawnmowers on display in B & Q, just to get a look at them, Like the new Bosch, but prefer the metal height/lower handle on their own make, but don't like the cloth collection bag on that one - just need the two mowers to combine certain bits and it would be fine.
Also as you say it's usually me who cuts the grass!

For many years I used an electric mower that mulches as it cuts. This was not only good for grass but come fall I ran over the fallen tree leaves with the mower and mulched them too. So, you might consider one that has a bag but also comes with an attachment that can convert it to one that mulches.

Having said that we chop the leaves with our ordinary petrol mower and use them as mulch in the garden or pule them up to rot.

Have just had a look on Amazon and there are several good makes on there at reduced prices if that's any help.
If you have a Screwfix locally you might get a better bargain than in a local shop when you've decided what you want..

My son actually bought me a mower from Lidl it was less than £50 that was five years ago it's still going strong my daughter does both our lawns and apart from bending the blade with a tree stump, she never looks where she's going, I got a replacement blade from amazon and a nice man at my local lawnmower shop replaced it free of charge, hopefully it will last a bit longer. You don't always have to spend a fortune,
