Head Magnesium 1000 racquet...

Hey (I'm new to this forum), I just picked up this racquet, the 'Head magnesium constant beam oversize' racquet and I was wondering if anyone knew anything about it or could tell me where I could find something on it. I've checked all over the net and haven't found anything yet.

I got it used for $15 at a thrift store, I'm 22, I've only been playing Tennis for the summer, but it felt pretty good to me. I've been using my friends racquets and this one feels pretty much the same size/weight only it feels like a much nicer racquet. If my game gets better I'm sure I'll pick up a nicer racquet eventually, but I was just wondering if anyone could help me out with this one.
