I bought a mid level Gnu board couple years ago and it's fine. Any burton is probably as good or better. As long as 158 is tje right length for yaBurton is 158cm and 5150 is 159cm. that works out to ~62 inches.
i actually did some searching about the 5150 brand. one review said "5150 is the armpit of the K2 corporation" so i think i'm going to pick up the Burton
