Yeah, I used to own an Oxygen board. I knew then that it was a pretty basic board. It lasted me two seasons surprisingly with moderate use (once a week). If you are looking at Oxygen I would compare them with the Lamars of the market. They aren't that great but they WORK...at least for a while. Hope this helps!
There was a time when Oxygen was the shit, much like Lamar, Sims, Avalanche, Liquid etc. If I remember correctly they were bought out by another comapany and it was all downhill from there. I haven't heard or seen much of them in about 4-5yrs though.
