Looking for a pellet insert

I am looking to get a used pellet insert but I am not sure what to get, I have a Harman P61 in the basement, but I would like to get a pellet stove for my fireplace. I am only heating 1000 sq ft of a raised ranch. I like the Harman because it is easy to clean, but I have seen some Quadfires and Breckwells for a good price but they were old and I am not sure how easy they are to clean. Should I be concerned about a stove that is 8-10 years old? And would an Accentra insert be to big for what I need? Just to add I have insulation between the ground level (basement) and the the living space which makes it tough to get the living space heated from the P61 that is in the basement, and I have no where to put the P61 in the living space.

Thanks

Thank you for your reply's. The ground level (basement) usually gets up to 83 degrees and the upper floor is usually 70 depending in the outside temp. I was thinking that I would use less pellets if I had a pellet insert for the upper level, went through 3 tons already. On really cold days I burn wood in the wood stove insert. I guess my problem is getting the heat from the basement to the upper level, like I said the ceiling is insulated between floors. Right now I keep the door open leading to the basement and have a fan blowing the heat up the stairs. I am not to keen on cutting holes in the hardwood floors to transfer heat. So I would like to get away from the wood insert and hauling wood to the upper level, yes I know I will still have to carry pellets upstairs but it's a lot cleaner than wood.

Thanks
