I'm the original owner of my '90 WS...bought for me when I was in college by my then girlfriend now wife...mine is also in excellent shape,,,14 speeds, indexed shifting..cromolly main tubes...alloy rims...it's nothing spectacular, but just a very solid rider...in my neck the woods you got it for a fair price if it's in pristine condition...I'd have to double check mine, but I'm pretty sure it's a Giant made frame...(SN begins with G)

here's a pic of mine,,,,forgive the non-drivetrain shot...
