I find it hard to understand why comments about the price of an item should be brought up in a post. If you think that a price is way out of line, PM the OP with your concern, as they may just be ignorant of the value of an item. Prices usually get adjusted over time and you can always PM an offer.
As to this lens, I have to agree that it is a very fine lens and is no doubt worth the price to the OP.
When I have sold items on the forum I have usually placed a price as to what it is worth to me. Sometimes it has been low and it sells quickly and sometimes it has been high and I have adjusted the price or taken the item off sale as it was worth more to me than I was willing to sell it for.
