I've just been searching them.
Seems that they have some custom scatter guns that have sold in th UK for upwards of 600k. NOt sure if that is Euros or British £'s
Also saw a few articles stating that quality for the avg shotgun is a hit and miss thing.
Maybe you ought to call the retailer to see if they have a few in inventory that you could look at.
Hit and miss quality has been the plague of Turkish guns. I don't doubt that these are the same.
Honestly in that price range I would be looking at a used Ugartechea or SKB. Don't get in a hurry to buy and you can find a deal on a quality gun that will increase in value instead of decrease. I mean the $700-$800 range. I lucked out and bought a nice Merkel model 8 a few years ago for $650.
Here are some places to look besides the norm.
