poulan 6900

Does anyone have a good used or new Poulan 4400 or 6900 cylinder, or know who might? I am looking for one.

Greetings all, I have a desire to resurrect my Poulan 6900 Professional that was my first chainsaw out of high school. The piston and cylinder need replaced as the cylinder is scored. Everything else seems to be in order and it is a well built and rugged saw(a little heavy too). Does anyone...
