I need to choose a skateboard?

k, i'm a new a skater. I can ollie pretty high for a begginer, but i still can't do it while moving, because of the following (i think). The board was a hand-me-down from one of my friends, a birdhouse. That's just the deck. One of his friends gifted me the trucks (fake) and the wheels (rubber) and berrings. they where missing two screws and my friend, being a dumb ****, while putting the board together, threw a piece away. it worked fine for a while, but now it's loose, and when ever i gain speed, it swerves, when ever i try to balance, it tips over so, i need a new board. so my friend recommended a toy machine, but, i'm not sure. Any recomendation? for the wheels too?
