Boy, did I hit a sore spot or what? These are only rifles that we are discussing, not family members or trucks!
Sorry, to get back on track: My experience with Handi's has not been as good as expected. I had thought that I could take the rifles as purchased and use them as anticipated. My previous experience with single-shots was with Rugers, and I was very happy with the 2 that I had. With the .223, all I wanted to do was to get the rifle, work up a load, and go 'chuck hunting. That didn't happen because I did find a load that would group as well as I expected, but wouldn't repeat group placement. I prefer to spend the little free time that I have using the gun not screwing around with it.
As far as resale, a used Handi will retail for $130 to $150 around here. I don't know about the Stevens. From experience, I would think around $200.
The Handi will accept multiple barrels, but this requires fitting by the factory or the owner, if he is capable. You are out of luck with a Stevens, it is what it is, unless you want to pay what the gun costs originally to get it rebarrelled, and then you can't switch barrels. One thing that H&R could do is to make the barrels completely interchangeable so you don't have to send the action back.
The only reason I didn't get a Stevens was that the Savage was on close-out, otherwise I would have cost $100 more than the Stevens at that store. I did try the trigger of the Stevens and it was acceptable, although the accu-trigger was much better. I would not have bought the Stevens and put an after-market trigger on it.
