I've had some of the single shot models of these. I still have a 16 ga single shop NE Topper. Really good shooter. They are pretty inexpensive and not all that hard to come by. I'd buy another if one come around and I had the cash.

FYI the New England Pardner Protector/pump and the H&R Pardner Protector/pump are the same thing. The original company name was New England Firearms, and the exact same product is now being sold under the Harrington & Richardson banner. I have an H&R and I can't say enough good things about it.
I have the H&R Pardner 18.5" barrel and love it. It's nice and heavy and shoots great. The only complaint I have with it is that it does not like PDX brand ammo. It ejects but I have to pump it twice per shot to get it to load. All other brands it performs flawlessly with.
