Push Mower

I have a Honda Izy (painted pink) which I intend to keep. See avatar.
To take the mower to the back lawn I have to pick it up and carry it. At 28 kg and having to keep it upright it gets a bit awkward to carry.
I am considering a push mower so that I can mow after the kids have gone to bed and hopefully it will be easier to carry. I am worried about the wheels slipping though which is something an old (free) push mower did on me frequently 10 years ago, hence it being binned. I would also like something with a high cutting height (at least 3 inches).
I fancy the Fiskars Staysharp Max (doesn't everyone) and also the Webb H18. Both use contactless staysharp blades. The Webb is £100 or so cheaper than the Fiskars, plus it has a roller and a bag. The biggest downside to them both is the weight. Both around 22/23 kg.
Does anyone have any experience of these mowers? Any recommendations gratefully received.
Thanks

In the 11 months since I first posted, I think I can rule out the Fiskars on cost.
Perhaps a revised set of questions is in order.
I have some moss. Is this a problem to a hand pushed cylinder mower?
Some mowers are light weight such as an Alko or Bosch. Others are heavier such as the Webb H18. Does the weight affect the performance? I don't want it to lose traction.
Has anyone any opinions on the Webb H18? This is the bigger of the two Webb hand pushed mowers. It looks nice.
Thanks
