Insert for small fireplace?

We recently moved into a house with a fireplace, but its dimensions are pretty small for an insert. What makes the installation difficult is that the sides of the fireplace do not go straight back, but go diagonal into the back of the hearth. The rear of the heath is appx 17 1/2" wide, and its about the same depth. (Prior stove in old house was a Jotul F3cb)
Only insert I have seen out there so far that would fit is the Quadrafire 2700, but from some reviews it seems like this isn't the best stove to get.
Setup is that the fireplace is on an exterior wall, and the chimney faces exterior on three sides. (I would be relining the chimney the whole way up vs just 6 feet into the flue)
I originally liked the quadrafire as I would not have to build additional hearth protection, but from what I have read online it seems like there aren't a lot of positive comments out there for it. Any suggestions for a small insert would be appreciated.
House is a colonial, and the insert wouldbe placed on the 1st floor. 1st floor is 864 square feet, and the room is with the insert is 12 X 36. Thanks for the help/comments!

Lopi Answer/Revere, Osburn 1800i, Napoleon 1100, Hearthstone Morgan or Homestead (hearthmount config),

Remember to look carefully at all their manuals for the depth of each stove and then measure the width of the fireplace at that depth. Hopefully you'll find that one of these fits. The Hearthstone Homestead basically avoids a lot of the problems by being a free standing stove with shields to aid installation. No size issues I suspect. And a darn nice looking stove too.

If you get an insert, (other's may dissagree) but get a blower. I've used my stove with and without, and the stove is twice as effective running the blower.

If it is a pre-fab fireplace, you could remove it and replace it with a high efficiency fireplace. That would give you the efficiency of an insert but take care of your space problem

Wow, unless they have came out with a zero clearance epa fireplace that is tiny, i cant imagine firing up a 60k-90k btu fireplace in my bedroom. The Quad 7100 i have on display here will heat my 3000' showroom all by its self. And my showroom has glass on all sides and a uninsulated metal roof! In my area they dont allow wood burning products in bedrooms anyway, only direct vent gas and pellet stoves. Pelet stoves dont require a permit in my area.I dont think the belong in the bedroom any way due to noise when the unit cycles, and in a horizonatal install they will smoke during a power outage. But in this thread, if i had two choices, pellet or coal, i would chose pellet.

Hi folks....the fireplace is in a family room which opens up to the kitchen. Not sure where the bedroom idea came from. Thanks for the comments.
