As the title says, we have to buy our first lawnmower and we have no idea what to look for.
Our budget would not stretch over £75 unfortunately, and I've seen some within that budget online but the reviews confuse me, to say the least. I saw a few Flymo ones but some buyers say it's the best purchase ever while others say "avoid avoid avoid"
On a particular model a buyer said you'd be better buying a goat, as it'd do the job better 
This is our first garden, it's a fairly big rectangle, only grass, no plants or anything (yet) It's about 6x20mt.
Any advice will be hugely appreciated. Thanks!
