Jonno mate you need to take some time to get shit together,
your How old ?
& good tools cost good money,
now many will say what they like,
I like Snapon & yes i buy if i can,
But you will look about se some good quaity tools at a good price,
so i would say to you ,
get a small 1/4 socket set ,
then Build slowly from there,
i use a small set on my car most of the time,
& when i need 3/8 i use that,
Good luck
