Interesting question, but it is not limited to Talon Khorus. Occassionally, there will be a glut of a particular item on the used market purely by coincidence. This has the effect of driving the prices way down. After most of the items have been sold, the prices usually come back up. As an example, I bought a BAT VK5i about 6 months ago for $2200. At that time, that was a decent deal. When I put mine up for sale 1 month ago(to upgrade to VK50SE), there were 7 units on Audiogon. Some people are more desperate than others and drop their prices. Some were sold for as low as $1850. However, there are fewer on the market now and I can afford to wait to get my asking price which is fair. My recommendation, take advantage of the gluts.
