it actually depends on where you go and what kind of board it is
boards that have images in it is about 40-100 dollors

i suggest you get a blank board with some normal trucks

maybe some cargos or thunders

i suggest thunders

and like i said there is no such thing as a cheap board

a blank board with thunders will cost you about (including griptape)

is about

75-80 dollors plus tax

trust me im a skater

i suggest you go to your local skateshop

Dude go to a1skateboards.com

they have radd and sturdy good boards, specially for street skaters. like if you need real cheap ones that are at least standardly good, get the Speed Demon decks there. or the 1031 decks. i skate those. or Goodwood skateboards. for trucks, the cheap ones would be Mack Trucks and Cargo trucks, but i agree with the other guy. get Thunders. its worth it.
