>>842098skater here, if you are wanting to street skate you better be ready to go through shoes bi-monthly and spend a lot of time bashing your shins when practicing the same movement.
learning to ride to get to the point of being able to handle well around the streets and bomb roads well will take a couple of months, during that time you will meet a whole load of skaters and bmxers that will talk to you and give you tips.
its not to expencive for a setup (mine is cheap at around £140) and should last you long enough to get basic tricks down (ollie, manual, pop shove ect...)
if you get into it you will make life long friends, good cardio and leg gains, new skills and a new mode of transport.
