Best kept secrets in tele lenses?

Danny,

Not sure you got my drift on all this.  I was just wondering if Olympus made decent lenses that would not break the bank.  Top quality lenses often do cost too much(for me).  But once in a while, a really decent lens comes out that is also economical.  I was asking if there are any 200mm to 300mm tele lenses for my E-pl2 that quality as one of these "well kept secrets"?
