Is this a good deal?

Depends on whether you can find a glass for the front door and whether the firebrick or liner is missing or in good shape.  I would try to find out the manufacturer and check on the glass availabilty. Might have more in the glass than the complete cost of the stove.

But if worse comes to worse you could always substitute the glass for metal plate.

I have this exact stove.  Good deal at $75, especially if you don't need to travel far for it.  I plan on using our verion in our camp once complete (or else my Franco Belge wood/coal stove).  The glass is actually panes of mica that you can get pretty reasonably at a stoveshop or online at places like Woodman's.  Downside to this type of stove is that there's no ash pan for cleanout, making it a bit messy, and it's constructed in panels, so unless you cement up the seams really well and install good gaskets, it's not remotely airtight.  I would get a 4 hour fire out of mine with everything buckled down tight prior to sealing it up.

I have no idea what brand it is
