The price could vary greatly depending on the installation, and what parts can be saved and reused (Hearth/mantel etc).
Are you talking about a free standing stove or an insert?
Are you going to do this yourself?
Here is what I ended up doing:

I saved and reused the marble hearth, and mantel.
All the rockboard, drywall, tile, mortar, wiring, cost approx $500.00
The rip out and rebuild took 40 man hours, but I did this work myself, and I'm a very qualified person.
The stove installer charged $650.00 (labor only) to come put it in the wall with venting and OAK.
The installer charged me $632.00 (Materials) for a 4" vent and OAK (I requested 6' vert set up for good drafting, and a cleanout Tee).
If you are looking for an insert install you can save yourself a lot of work and money if you can use the Harman Accentra insert because you can purchase a zero clearance box for a bit over $200.00 instead of building one yourself as I did.

Look up the technical install manuals for each unit online, and you can look for yourself what's entailed.
I went with the re-badged Enviro M55 for it's BTU, and I extremely happy with it, but it is totally overkill for my house.
I'm now sure the Accentra would have worked, but we haven't hit the cold hard part of winter yet. ;-)
You can add the cost of your stove to this for a rough idea if your install is similar.
