That weight is NOT something you want for a lot of clay target shooting - you would be better off with a gun about 2# heavier, otherwise the recoil is going to become bothersome.
IIRC, this gun is made in Turkey; depending on WHICH Turkish maker may or may not be an issue
If you want a semi for skeet and sporting, look for a used Beretta 390 or 391 in your budget range
I have a CZ712, I bought to shoot occasionally. I have had no problems through the first couple hundred rounds...not much I know but that's about the limit of my shotgunning. For those talking them down, I'd be interested to hear some details on what you think is "sub-standard" about them.
