Back when I was a ski tech, the store I worked for kept me busy building and working on bikes in the summers. Most of the time when we'd see a bike that is all painted up (Mountain Dew, Bud Light, etc) it is almost always a promo bike that was a giveaway at a bar or some kind of event and has all the cheap components: SRAM Grip shifters, Shimano entry level derailleurs, etc.
The listing states it's a "one of a kind" and then goes on to say there is one listed on ebay? Even if this frame fit you perfectly, it's still not worth $150. If you want something cheap to beat around on, you can go to Sports Authority or Dick's and get a Barracrappa or something similar with gripshifts, linear pull brakes, aluminum frame, Shimano derailleurs for right around $160.
Best bet, if you think you're serious about getting into riding: save 500 bucks, go to a bike shop (not a store that also sells bikes) tell them you want something to start out on but also be worth making some upgrades down the line.
