Apparently they use the same motors as Hayter, feel quite well built, have variable speed which I thought made sense as aged parent gets older. Also grey, not red or orange which most of them seem to be.
If we go down the self-propelled route, variable speed definitely sounds like a good idea for our garden, which has lots of tricky bits to navigate and tight corners.
Out of interest, what was the Weibang model you got? Have you used it yet?
Looking at the aforementioned local mower place, even the most basic variable speed Weibang model they stock, the Virtue 46SVP (at £500) is 2.7kw, 46cm blade and 55L clippings bag, compared to our Flymo's 1.8kw, 36cm and 26L.
I really haven't appreciated until now quite how crap our Flymo is! (Well, it's probably fine for a small garden with a flat, square lawn but really not up to the job for our garden. £500 feels like a lot to spend on a mower but it seems to be a reasonable ball park figure for something that will be capable of taking the pain out the job.)
