I bought Velda through publicsurplus.com from the Adams 12 Five Star School District in Thornton, CO (just north of Denver). The price was right at $2025 (I was the second bidder), and she came with automatic chains, brake retarder, and a whole bunch of heaters. Unfortunately, it turns out that the brake retarder is fried, and I still haven't checked out whether or not the automatic chains work (chains are illegal in WI, where I'm doing the conversion).
The fleet manager at Adams 12 has not been particularly helpful in obtaining information about the bus, and it turns out he FLAT OUT LIED about some other things...like the mileage. It was advertised as having 175K miles on it, but as I drove across Nebraska I realized that the odometer was not working correctly - it shows about 70 miles for every 1500 driven. And the fact that the odometer didn't work is documented in the service history for the bus, which I was able to get the district to email to me. Nevertheless, he just signed the release to title and left the odometer reading blank (illegal), which I didn't catch until after I'd arrived in WI and took the time to look at all the paperwork I'd accumulated. So even though the price was right, I wouldn't recommend buying through Adams 12. But publicsurplus.com has lots of buses all over the country, and I bet you can find one from a different district in the state for a good price. It will help that you're in the area - I was buying sight-unseen from Alaska.
