It's a Sportastic Supreme. Sportastic bought the Kneissl moulds when they stopped making tennis racquets last year. Tom Martinez said it's basically a clone of the Tom's Reach Machine/Reach Top Machine that Melzer used during his junior and early pro career. Just do a search on Google for "Sportastic" and you'll get their website. Pretty expensive frames for a new, unknown brand, though.
