Pros
Adjustable trigger, usually good accuracy, detachable mag is one of the better designs, two position safety with a secondary release to open the bolt without removing the safety.
Cons
Rifles can be a little on the heavy side compared to Remingtons or Winchesters. 300 rounds in one of the magnums (7mm WBY or STW) is not mint but is 10 to 15 per cent of the barrel's life. In one of the milder cartridges, it is just broken in.
Rings a little on the heavy side but solid. Get the low rings unless you are mounting a 50mm scope. Leupold rings for Sakos are crap. Warne rings are the best.
Detachable magazines are expensive to replace.
Conclusion
Not sure what the prices are like in your area but $850 sounds a touch high.
I like mine in .223. The frame is designed for the shorter cartridge and it's a little lighter than the larger calibers.
