It seems to be selling for around $120USD or so (plus shipping) on Ebay these days. I paid about $140AU total for mine, as I wanted a good condition example, and this particular example included the plastic hard case, both caps, and a lens in reportedly excellent condition. I was not disappointed when it arrived, the condition was like new. For anyone interested the seller was petersburg_deals. Shipment was quite quick considering it was from Russia.
Down to the lens itself. I find it to be very sharp, but I have only tested at f2.8 and f4.0 so far. Most reviews say the lens is a little soft at f2.0, but the kind of softness that works great in portrait photography. I find the colours to be great, let me know what you think. Here are the first lot of test shots.
Very first shot with the lens mounted on my K200D. A friends free promotional mug at work. This is at f2.0, but doesn't give a good indication of sharpness.
This is an f2.8 test shot, unfortunately the light was very uneven, but you can see the lens is sharp.
This is a 100% crop from the previous image, showing how sharp the image is. No post processing sharpening has been applied (click the image to view at original size).
