If you're okay with a "previously owned" gun, then you can probably find some "cosmetically challenged" S&W and Ruger revolvers out there.
There are many "night stand" model 10's out there which come back into circulation as the owners die off and their spouses get rid of the guns. Look for a gun that has some cosmetic flaws but shows few signs of being fired.
You can often find an ugly-finished S&W Model 15 with just a little wear on it and make it prettier with some elbow grease and a little sweat.
In this case, the stainless Model 67 above had a badly scratched left side which I polished out. The dealer sold it to me for under $300. A friend bough a blued Model 15 like the one above that was kept in a sock drawer near a bathroom for 20 years. Lots of little rust "freckles" on it and some larger rust spots on the grip. 98% removed with just a little work. And some quick cold blue it looks fairly good. All for just $235. With S&W steel revolvers you can use +P on any with the model number stamped on the frame (post-1956).
Don't overlook an older Ruger Security Six either. If the gun is in good mechanical shape it's generally a good buy. These were Ruger's first double action wheelguns and they kept them close to the K-Frame size for marketing reasons. These make excellent home defense guns. The Speed Six and Service Six were made at the same time and generally is a fixed-sight model.
