Query: the buck bangs big on this lens!

For $86 to my door, this lens has wowed my friends and family with some amazing portraits and nature shots. The background blur is fantastic when focusing within 2-3 feet, and the clarity is exceptional. I just couldn't be happier. Who cares if it is plastic. This compares with other $500+ lenses, meaning you would have to buy at least 6 before losing money to the others for equivalent performance. It's definitely the first lens you should consider to buy when upgrading to SLR from point and shoot. It is a real confidence booster for the novice (my wife, for example; she can't put the camera down now!)...
