To new members who are posting (with MPD and no coach yet). You may quickly find yourselves like a sailor with 100 dollar bills falling out of his pockets at Times Square during New Year's Eve with some of multiple-coach owners here...they just might want to sell you a bus.
There is a forum near the top of this site called Ah, Nice Coach which is a good place to chat about your ideas and garner some comments about one or another.
There are also those who work below the radar, seeking out and finding great deals on their own and then tell the rest of us after the deed is done. We can usually tell when MPD is at work because they stop talking about maintenance and begin griping about their 'Coots stock value.
Best advice to all is get thee to POG IV and meet people in person. Most of them are much nicer in person than they are online. It's easier to take pot-shots at home in front of a computer screen if you don't have to look the other guy in the eye. There may even be a bus or two there offered for sale?
