That exact guitar was my 1st (if the one you're looking at is blue.) I bought mine in late 1989 for about $350, and sold it approximately 9 months later for $300. I got the best part of that deal.
My own experience was that it was a huge pile of junk. The pickups sounded OK until I tried playing at a volume loud enough to hear over my brother's drums, then they became so microphonic it was unplayable. Mine held tuning adequately, but not perfectly. The hardware was pretty low-end. It did give me a great test-bed to learn how to do my own maintenance and setups.
It looked kind of cool, if you're into the '80s shredding machines and the crackle finish, which I was at the time but have since drifted away.
If it plays well and stays in tune, then it may be worth $120 to you. I wouldn't own another one, but that's just me.
Hope this helps!
