For me if I was going to spend money on fuel it would not be on pellets. Oil or propane are similarly priced and really no work. None of those work without power. That is just my opinion doesn't mean yours is wrong. I just don't like pellet stoves very much personally.
For me, pellets are way cheaper heat. Even if the cost broke even, my old LP boiler heats the unfinished basement as much as the living space. So I keep it on standby for emergencies only. A new whole house heating system would be a ton of money in any case. The house came with a Generac so outages have not been an issue. All costs for the stove was about $1200. Also the pellet stove is simple to monitor and repair if needed. Works for me.
