I need one of these

I am now thinking (ouch that really hurts) that I really need one of these

for if and when I sow some grass seed on my lawn. It wasn't looking very well today it looked tired (bit like me) old (again bit like me) but with a pick me up it should look fine, (again bit like me when I've got my face paint on). Here is another one which one should I choose ?

Actually that could be me after a hard night on the town.
