I need help - there's just too much to choose from...

We've just laid the turf in my first landscaping project, namely, my garden.  The lawn is somewhat smaller than when we started, about 50sqm now.  It's circular (except where it merges with the fire pit) all flat and surrounded by a wall.  I think we need something that will cut up to the wall and we're not sure if stripes will work?  It's nice turf as there are no kids/animals/through traffic and everything I've read and been told so far recommends getting a cylinder 'v' a rotary but I thought the Bosch Lawn Mower Rotak 40 looked like it might do the job nicely - does anyone have any thoughts???

There are pics on my page so you can see what I mean.

We have a big petrol lawnmower (something like a Castelgarden from Lawn King with a Honda engine) lying at the back of the garage but I think it's a bit big for the job...can anyone recommend how I can sell it - obviously when I know all the details ;-)

I'd be grateful of any advice
