Wanted: Looking for 30 inch over/under or semi auto shotgun

Looking for an entry level 12 gauge shotgun with 30 inch barrel with changeable chokes. Prefer semi auto sporting shotguns but would look at over under, looking not to spend too much for an entry level clay shooter. but show me what you have please, looking for Edmonton area only. Maybe like an Stoeger M3000 or a Tristar Viper G2 in 30 inch, something like that. No left handed guns please.
