Cheers, and thanks for your input - I am arrangong a demo next week, and yes
I knew stiga was Scandinavian and quality seems excellent. Apparently (may
be sales talk) councils use this make and they use the pro version which
gets lost of abuse.

Size of garden may be an overestimate, it's in two halves so I get a
breather between doing each bit and the reason I'm getting this mower is
because the man who does it is ripping me off - £30 a time every 10 days or
so, so its costing me £100/month!

Also I do need the exercise - I will post my findings/experince to the
group when I have it.
