Stove Recommendations

Since my Wonderwood turned out to be less than a wonder ...

I'm heating a 300 sq. ft. tiny house in southwest Tennessee. Our coldest nighttime temps generally hit the mid-teens and our heating season runs from mid-October through the end of February, although on many of those days I only need a fire at night. Obviously I'd like to get away with as little money as possible, but I don't want a stove that is so cheap as to be inefficient and a pain to deal with.

What should I buy?

*Edited to add that I love the idea of an RMH but don't have the ability to build one. I need something I can purchase ready to install*

Hearth.com is probably your best resource for such advice.  It's a forum dedicated to wood stove heating.

here is a place selling small stove s  -- I know absolutely nothing about this company, but it caters to mobile tiny homes     https://www.tinywoodstove.com/product-category/stoves/

Our small cob studio on my property uses a used, vintage cast iron Morso Squirrel and it works very well. I think the cob studio is 500sq ft, and it gets hot quickly with the morso squirrel, usually one small quick fire a night in winter is all that is done.

Morso still makes small stoves, more expensive than the dwarf stoves, but a very long track record

here is one link to show what it looks like and price, likely you would buy it from a local woodstove store in your area, or get lucky like we did and find a used one

mine looks like this, but no glass window, so mine is older than this link but otherwise has this shape.
