Are these shotguns any good? I know there are preferences that certain people have. Long story short, I am looking for a light weight 20g that I can take with me on a pheasant hunt this winter. One that is easy to carry, swings well,shoots well and is affordable.

I have found the build quality pretty good, though never really wrung one out for actual point of impact of the barrels. There is a whole subforum on them at Shotgunworld.com.
I will say this in their defense:
Weatherby just added a side-by-side shotgun to its Orion line and they are made by Yildiz.

I've had several Yildiz guns; all functioned fine and were good value for the money.

I currently shoot a Yildiz .410 for skeet when I'm not shooting my Franchi 28 ga.

Recommend you get the steel receiver model.

Only complaint I have heard is the action is noticeably tight, but they will loosen up with use. I opted to buy a CZ Upland Ultralight All Terrain 20 gauge. Really like it but man it is light and rather punishing on the shoulder even with promo loads. 3" waterfowl loads are pretty brutal, I'll take the autoloader for those.

Agree they tend to be tight at first, but so is my CZ G2 Bobwhite 28. It is loosening up nicely now that I have 150 rounds of AA's through it.

Get a secondhand AYA No4. It'll do all you ever need and be better by far than the YILDIZ.

Looks good, shoots where I look, and very good price. (.410)

If I wanted a double for less than 2k, here it is.
