I was in the same position a year or so back, bought then and have kept an eye on prices since as well.
My impression is that prices haven't dropped significantly in the last year, it seems to be more of a case that there are two sets of people selling - ones who actually want to sell and ones who want to hold out for a particular price.
Certainly a year ago when I was looking to buy, there were a few R930s and y88s in the $35-$45k range, a Chico 30 and davo 28 both asking low 20s, as well as a marauder and a E7.9 asking high teens. But there were some crazy high prices being asked
