Jeff,
I have no experience with Echo saws, but if you are set on their equipment, I'd look at the CS600P or CS680. From looking at the parts manuals for each saw, they look to be pro-built with a vertically split case with a separate cylinder. A good thing for easier access to the piston. Try a search (here on AS) on these saws to see what actual users say about them. I have read that some folks feel they're underpowered for their weight compared to the other brands. Go and handle their saws and see if they'll let you cut with one and go from there. And I agree with Andy's suggestion of a 70cc saw if possible.
