A couple years ago I paid around $3800 for a new Vermont Castings stove, parts, install, chimney cleaning and removal of the old stove. Labor was $345 but all they had to do was carry it in, sort out the pipe configuration and plug it into the chimney.

Everyone's situation is different. Maybe visit your local woodstove store and talk to them. They'll probably come out and look at your situation and give you a quote.

Note: If you're planning on burning this winter, expect to pay north of $400 plus delivery for a cord of kiln dried wood, if you can even get it. "Seasoned" wood needs more time than you've got to burn this winter.
