Looking at this price and the price you quoted i think I would be jumping all over it - if'n you like thumbhole.
Doesn't look like they have the thumb & fluted...
And then I forgit to add z5 vs regular Omega... Blue-ed barrels the same, Sights not the same, Black synthetic stock the same.... Trigger Group - according what I was told by TC the difference is really in this group. Regular Omega's have a couple of very small set screws in the pivot pins that allow you to dissasemble the trigger group into parts - the z5 does not - I think that is what the tech was telling me... I had called them to ask about the differece between a z5 black synthetic and a regular black synthetic...
