Went to visit one of sons. He showed me some saws he came by. The firs one is one he found in a dumpster. came with the case and a spare chain. a $10 part and it is up and running. The second one was given to him from a guy down the road from him who burns wood, but is afraid to use a saw.
You might want to be careful on the dumpster saw..just in case someone stole it and couldn't get it to run and dumped it ( or thought he was going to get caught )
