Thte TOZ is by far the best $100 I ever spent on a new rifle. It shoots real straight. The fit and finish is a little to be desired, so if winy fixed that it might be worth it at $250.
From what I read about 6 months ago, but don't quote me on this, the rifle is the same with the following "improvements":
Bolt (and maybe trigger) polished (that is really all it needed).
Better walent stock.
Bolt handle and positon changed, more winy like
Standard 22 groves on rail instead of euro 11mm
Different sights, worse front site but both front and rear iron (plastic rear on toz)
Mags still plastic (but hopfully the locking grove/notch is improved)
This isn't fact just what I remember reading awhile back.
