My 16" Saiga 308 is great. One suggestion if you intend to buy one, however, is to look at the front sight. It is pricey to modify the position of the front sight so make sure you get what you want. A muzzle break usually requires threading, so make sure its there if you intend to get a brake. There is also a bolt on brake but it requires 3/16" clearance between the sight post and the end of the barrel. Make sure its all there in what you buy because you may spend more making modifications than you paid for the weapon if not.
The reason why the brake is so important is that without it you tend to get a fireball upon trigger pull which distorts your sight picture and requires re-acquisition of the target every time you fire.
Have fun tricking it out. A forend, foregrip, pistol grip, piston, rails... there are so many after sale components available that you'll enjoy the heck out of it even before you take it to the range!
