Snow Blowers

I am considering purchasing 927SB snowblower from a neighbor. He bought it a few years ago and has only used it twice. I would like some customer reviews of this machine, its original price, how many were produced, why it was discontinued, and what existing machine replaced it. It looks brand new. He says he "prefers to shovel for the wonderful exercise". I hate shoveling! Want a quality machine at a good price.
