Right now there are some good looking buses in Washington State on the Public Surplus site, if anyone is interested. Among them is a Gillig. I actually saw this one in person before it went on sale when I was looking at another bus. Seemed pretty solid at the time. Here's the link to Public Surplus. Plug in the item numbers in the search to find the individual buses.
Sometimes you can get buses really cheaply here, other times not. Depends on who is bidding.
