The issue with Turkish double guns comes from barrel regulation and really gritty triggers - this is most often found from guns made by Huglu. UTAS is a Turkish company who makes excellent products that are not built to cheap price points. Double guns require more hand fitting and labor to do properly. If the price is cheap, it means some of the steps were either omitted or done so quickly and poorly that the expected quality isn't there.
It isn't that Turkey can't make good guns, they can - but if you want a double gun AND cheap, IMO, you would be better off with a better quality semi.
There is a Spanish O/U from CDNN (Lanber), that is in your range, otherwise you can find a used AyA originally sold through Sears. While older, if in good condition, it will be well-made, barrels properly regulated, and decently balanced
