Budget side by sides
I have bought two side by side 12 guage doubles from Trade-ex, along with quite a few other rifles, including a Kimber .22.
Right now, there are a lot of quality double shoutguns on their website, including some BRNO and Sauer made guns. As mentioned, read their descriptions, click on the description for a larger view, and if you see one that you might like, give them a call on their toll free number. Anthony will also e-mail you more views upon request.
You can also check out the Gun Shows. If you look long enough, sooner or later one will appear, at a reasonable price. Ask around the local gun clubs, or Gun Shop. Some Gun Shops may let you put a small "Wanted" ad on their bulletin board. It is good relations, and such a service may not make them an immediate sale, but you tend to buy other stuff from someone who helps you.
The two I bought from Trade-ex were a Hungarian FEG Victoria Grade with ejectors, and a BRNO with ejectors and a broken stock. The broken stock reduced the price to a low amount, but I accepted and was prepared to repair the stock, or make a new one. It was to be a field gun not a collectors piece, and was to be used for bird hunting. I epoxied the stock back together, and inlet two steel rods epoxied into the wrist to reinforce it.
A small piece of wood will cover these, and the checkering redone. For the sum of $150 and a few hours work, I have one of the sweetest bird guns a person could ask for.
