If you're looking for a high value sxs I'd either look at cz ringneck's (single trigger, prince of wales grip) or a bobwhite (double trigger, straight grip). They should be under the thousand dollar mark.
OR, start searching for a decent shape LC Smith, Ithaca, in a field grade. You might be able to find one in the states (or if you're lucky here), that has some scratches etc, that is in good useable condition. Prohpet River will bring one up for a couple hundred bucks I think.
http://www.cabelas.com/product/Gun-L...3Bcat103581180 2-3/4"" shells, and you may want to get a gunsmith to open up the chokes.
just an example. I think you'd be further ahead to get an older classic shotgun brought up than to pick up an IGA or similar. Just my opinion.
