I would stay away from Craigslist or Ebay stoves.
Reasons:
1) You do not know what you are getting, there could be unknown damage to the stove that could cause serious issues
2) Cost of repair
3) Time to repair
4) Price, when you add the cost of the stove, + the materials to repair it, + the time to repair it you really do not save that much if any over a new stove
5) No Warranty
6) Smoke Dragon and may not be EPA rated
7) If not EPA rated your insurance may not cover it
If you are on a budget I would suggest the Englander NC30 (Heats 1,800 - 2,200 sq. ft) or one of it counter parts (Summers Heat, Timber Ridge) that are sold at the big box stores.
They are EPA rated and from what others have said their customer service rates batter then most stove companies on the market.
Typical pricing on their large model stove is under $1K, when on sale and closeout people have been picking them up for under $800.
What you get would depend on the area that you are heating and how much you want to spend.
I own a Harman TL-300 which heats my ~2000 sqft home and can go 16 hours before re-loading.
If you really want something that goes along time between re-loads I would look at the Blaze King.
